Class 1 and 2 e-bikes limit assist to 20 mph, not 15. You can ride them faster than that, but you have to provide the power. 20 mph is well above what most recreational cyclists can maintain on a flat course, so if these classes arenâ(TM)t fast enough to be safe, neither is a regular bike. The performance is well within what is possible for a fit cyclist for short times , so their performance envelope is suitable for sharing bike and mixed use infrastructure like rail trails.

Class 3 bikes can assist riders to 28 mph. This is elite rider territory. There is no regulatory requirement ti equip the bike to handle those speeds safely, eg hydraulic brakes with adequate size rotors. E-bikes in this class are far more likely to pose injury risks to others. I think it makes a lot of sense to treat them as mopeds, requiring a drivers license for example.

Would treating them as mopeds be so bad?

What weâ(TM)re looking at is exactly what happened when gasoline cars started to become popular and created problems with deaths, injuries, and property damage. The answer to managing those problems and providing accountability was to make the vehicles display registration plates, require licensing of drivers, and enforcing minimum safety standards on cars. Iâ(TM)m not necessarily suggesting all these things should be done to e-bikes, but I donâ(TM)t see why they shouldnâ(TM)t be on the table.

I am a lifelong cyclist , over fifty years now, and in general I welcome e-bikes getting more people into light two wheel vehicles. But I see serious danger to both e-bike riders and the people around them. There are regulatory classes which limit the performance envelope of the vehicle, but class 3, allowing assist up to 28 mph, is far too powerful for a novice cyclist. Only the most athletic cyclists, like professional tour racers, can sustain speeds like that, but they have advanced bike handling skills and theyâ(TM)re doing it on bikes that weigh 1/5 of what complete novice novice e-bike riders are on. Plus the pros are on the best bikes money can buy. If you pay $1500 for an e-bike, youâ(TM)re getting about $1200 of battery and motor bolted onto $300 of bike.

Whatâ(TM)s worse, many e-bikes which have e-bike class stickers can be configured to ignore class performance restrictions, and you can have someone with no bike handling skills riding what in effect is an electric motorcycle with terrible brakes.

E-bike classification notwithstanding, thereâ(TM)s a continuum from electrified bicycles with performance roughly what is achievable by a casi recreational rider on one end, running all the way up to electric motorcycles. If there were only such a thing as a class 1 e-bike thereâ(TM)d be little need to build a regulatory system with registration and operator licensing. But you canâ(TM)t tell by glancing at a two wheel electric vehicle exactly where on the bike to motorcycle spectrum it falls; that depends on the motor specification and software settings. So as these things become more popular, I donâ(TM)t see any alternative to having a registration and inspection system for all of them, with regulatory categories and restrictions based on the weight and hardware performance limitations of the vehicle. Otherwise youâ(TM)ll have more of the worst case weâ(TM)re already seeing: preteen kids riding what are essentially electric motorcycles that weigh as much as they do because the parents think those things are âoebikesâ and therefore appropriate toys.

This might not be such a good idea as Vegas was begging Canada to come back. Their tourism isnâ(TM)t what it used to be and talk of 51st state has turned off Canadian tourism.

That's the press doing its usual lousy job of communicating science.

The predictions aren't absolute, they are sets of scenarios for which probabilities are calculated. The longer we drag our feet, the more the set of plausible outcomes narrows. Take Syria -- Syria was a wheat exporter in 1990, but since 2008 or so has been unable to grow enough wheat to feed itself because of climate change when it had become dependent upon imports from Russia and Ukraine. This was early enough that likely we could not have prevented it even if we heeded early warnings in the 1990s when the current scientific picture solidified. We're not going to lose the entire planet in one go, it's going to be one vulnerable population after another.

It may seem like the climate crisis has completely fizzled to you, living in a large, wealthy, and heretofore politically stable country, but it is catastrophic for the people who have got caught. That's how the climate crisis is going to unfold: the rich and comfortable will be able to adapt to the continually changing status quo by moving their financial assets and supply chains out of the way, although you may be paying more for coffee.

At this point it's a matter of degree; we can't avoid problems now like countries being destabilized by climate change and generating millions of refugees. The question is how fast and how big a problem we'll have.

It seems pretty plausible that sub-recreational doses of psychedelics could reduce anxiety, but we have to be mindful that anxiety evolved in our species for a reason. Like inflammation, it’s a natural and critically important protective process that gets out of control in modern lifestyles. It’s unpleasant but pharmaceutically banishing it could leave patients vulnerable.

One of the biggest risks psychedelic therapy will expose patients to are the therapists overseeing their treatment. Psychedelic therapy has an appalling track record of abuse by therapists, including both sexual and economic exploitation. Advocates for psychedelic therapy claim it will “open you up” and I think they’re absolutely correct. But there are other ways to say “open you up” that mean the same thing but set off alarm bells: becoming more suggestible and compliant for example. If the therapist uses psychedelics himself he may have “opened himself up” to some bad ideas about therapist-patient boundaries.

Likewise people microdosing to enhance creativity should exercise caution. Psychedelics absolutely can in some instances unlock creativity by turning down excessive self criticism, but those criitical facilities play an essential role in the parts of the creative process that come after coming up with out of the box ideas. Self reports of microdosing effectiveness should be taken cautiously, due to their potential negative impact on metacognition. Those might be like the drunk who feels more confident driving after a few drinks.

No doubt these drugs have tremendous potential to treat extreme crippling anxiety. They probably even have nootropic potential. But their beneficial effect s come by suppressing natural mental processes that serve important purposes, and the promising results we have come from self reports or clinical reports from advocate researchers. I’ve been following this because I’ve been interested in experimenting with psychedelics for years, but what I have learned has convinced me to hold off until there is evidence and protocols for safe use that would persuade a skeptic.

When I was in college (in 1995), this one guy was going on about a free OS that was incredible. All I could think of was, sure, a free OS that is good, what a joke is that going to be. So together with another friend we decided to install this free OS and have a good laugh.
The laugh was on us, it was indeed incredible, offering multitasking, multi user, memory protection, the cli was so powerful, and on top of all that, all the code was open.

they are competing against the Valve SteamDeck, which is their main worry as it could interrupt the dominance of Windows as the main pc gaming OS.

One of my neighbors whoâ(TM)s in his eighties wound up switching to a recumbent tricycle because he had balance issues. Which sucked. But the tricycle is awesome and probably would be comfortable for you to sit on.

Nevertheless, you should ride what works and is enjoyable for you. The point is not to punish 80-year-olds by forcing them to ride bikes they arenâ(TM)t safe on. I have an Azore city bike that I really like. Wouldnâ(TM)t mind still being able to ride it at 80.

I live in Europe. It's definitely not a utopia (nor is it a single country!). However, I don't think that being more like the U.S. would make Europe better. That's my only point here. Yes, Europe could definitely be better (even the European country where I live!), but being more like the U.S. would make it worse. Certainly going in the direction of "growth first" would not make it better, although again I'm sure some percentage of those who emigrated to the U.S. would say this would be better.

The country I live in now is becoming more like the U.S. at the moment in the sense of starting to move toward home ownership as a growth asset. In the U.S., this has caused an insane housing shortage, and we're seeing that here too. We should be moving away from such policies, not toward them.

That's because if you get to 75 years old in the U.S. you are more likley to be reasonably well-off—if you aren't you are more likely die before that of preventable causes. And if you are well-off, that helps once you're past 75 as well. Of course plenty of poor people reach 75 in the U.S., but percentage-wise fewer do.

Also, the EU is a big place with lots of different countries. I live in the Netherlands, where you routinely see 80-year-olds riding bicycles. This is less common in other european countries, but that's changing. Your comparison would be more useful it if were by individual country rather than including the whole continent. I don't actually know if it's any different in the Netherlands—we have income inequality issues here too—but it would make sense if it were because people are so much more physically active here throughout life.

At this point a lot of economic growth is just generating garbage, but because we are so addicted to growth, we have to keep generating garbage.

A better question to ask would be, would you prefer to live in Europe or the U.S.? Not work, live. The idea that our lives should be work from graduation to grave doesn't really seem like something we ought to be valorizing—it sucks for the planet, and it sucks for us.

Reality check here: hybrid solar farming actually increases yields, because a lot of crops don't like direct sunlight all day.

Really, if that's the way you want to live, I say have at it. Other people having the option to live differently isn't going to stop you. It'll be decades before it starts getting hard to find gas stations, and by then EVs will have more range than you can handle.

It is pretty hard not to respond to the pure BS that anti-EV types spout. I know it rubs you the wrong way, but the alternative is to let people who don't know what they're talking about dominate public perceptions.

I wouldn't claim EVs are for everyone, but for many of us they are extremely convenient and economical to run. The corner cases where ICE is clearly more convenient are not a concern for everyone, and not a concern for a multi-car household considering making one of their cars an EV. We have an EV and a plug-in hybrid that runs as an EV probably 80% of the time. We hit the gas station with the plug-in about once every six weeks.

I heard an economist pose this question once. Why do companies have employees at all? Why not use contractors? Then you could hire just as much labor as you need, when you need it, then not pay for labor when you didn't need it.

His reason was the costs involved with finding contractors then negotiating agreements with them. I think there are other reasons, but for sure that's part of it.

But I think technology is pushing us into an intermediate position between the semi-permanent, often lifelong employment of a generation ago, and a world of contracting for everything. I think this is evidenced by a pattern I have seen where companies who are currently successful lay people off. It's not just in the tech world, this is happening in the service industry too.

When technology allows you to monitor the financial performance and cost of every department in an enterprise down to a fare-thee-well, it's easy to identify people you don't need so much in the upcoming quarters and let them go. Then with Internet hiring and automated application screening it's easy to hire those positions back in a year.

Now there's a lot of holes in this rosy (for management) scenario. Automated application screening is dog shit, for example. But you can do it, and you will find people; probably not the *best* people, but then you'll never know, in fact *nobody* will ever know. People will never get to know their jobs well, but again you won't ever know what you're missing. Most of all you will never have anything resembling loyalty from the people you hire; young people these days look at every job as transient. But you can't *measure* loyalty and in most cases, job competence with any precision. But you can track costs down to the penny.
