1) Around here the cyclist only have one hand signal, and its to tel you were YOU should go.

As for you other points, I look forward to my car sending a video, date, and time of the other vehicle behaving in that manner.

no worse then the driver is now? Most people most of the time do not handle an emergency situation correctly. They may get lucky and avoid it, but is' seldom the best course of action.

You might as well ask the same question about anti-lock brakes.

"“William Shatner has been so generous with his time and energy in encouraging students to study science and math, and for inspiring generations of explorers, including many of the astronauts and engineers who are a part of NASA today, "

I listen to a lot of science podcast, shows, help with engineering programs and I have never heard his name in anything but an ST reference.

But then you wouldn't be able to drive?
oh, right, you drive so much better then everyone else..just like everyone else is.

If grid lock, anger, douch baggery, and killing automated cars is you goal, then sure.
Otherwise, we will just have the self righteous assholes going 15 MPH in a 25 MPH zone becasue they are too precious to use the bike lane.

I envisioned them as being rather like large tapioca pearls filled with water, and that they way you would "drink" them would be to pop a handful into your mouth and chew.

OTOH, "looks rather like a jellyfish" is subject to numerous interpretations. It could be just a floppy thing that come in pint and liter sizes.

Why do you think a filet mignon has bacon around it,

Mine don't, the only thing I add is sometimes a bit of cracked black pepper. If you can't enjoy a rare to medium rare filet without adornment then you don't really like the taste of beef (and then a substitute like TFA is probably fine for you).

The labs have to stop using gay rats.

The practical problem with solar is that photovoltaics are a poor baseline power supply, because for around half the day it's not available. There *are* solutions, but they're all iffy or expensive. Mirror based solar power is better, but largely untried. (New plants are under construction right now, however.) Unlike photovoltaics, though, mirror based solar power to molten salt to steam to turbine to electricity only makes sense in a centralized plant. Scaling it down to homes increases the cost remarkabley while at the same time reducing the efficiency and increasing the tendency to fail.

I do favor solar power, but batteries are lousy at storing power, so we still need the grid. And we still need to store excess power when it's plentiful and withdraw it when its needed. I think molten salts will provide the needed storage. This implies that the power generated by solar cells would be used as it was generated, and the molten salt backing store would be off-line until evening. That means that the current plans for the molten salt facilities are improper. They don't concentrate enough on storage. It also implies that the grid needs to be updated to allow bidirectional transfer of energy, depending on what is available where and when. Not a small amount of investment there.

But do note that the molten salt generator systems fill in the place that the coal plants currently fill in Germany, but with the ability to start relatively quickly, so they don't need to run all the time. You don't get away from centralized power plants (pity), but you do get a carbon neutral power source that doesn't require a bunch of externalities.

Surely BatMan would save us from that problem.

A reasonable attitude, but poor politics. Better would be to point out that the warming climate is spreading tropical diseases away from the equator, so that you can already get Dengue fever and malaria in the US. (Don't point out that this may really be due to increased population mobility.)

Because there aren't female predators?

FWIW, in a few places mosquitoes have been eliminated. It has not been noticed that any problems were caused. Not even for bats and swallows.

The real problem is that one can never forsee all possible problems. All decisions are made with a lack of certainty in the results. But when those who pay for the lack of foresight have no control over the descision made, it seems like either reckless abuse of power or worse. And sometimes it is.

If people with the power to make decisions could be trusted to make the best decision, a lot of the second-guessing would go away. Unfortunately, there is a very long track record of people in power making decisions based on benefit to them and costs to them, and ignoring the benefits/costs to everyone else. So there's a certain lack of trust.

To me this decision looks like a good one. I could be wrong. I'm not making it, and I expect to receive neither the benefits nor the costs.

It (or things quite similar) has been tested before on small islands with no problems. This isn't proof, but real proof is unlikely to be possible for that kind of question. On small islands it has successfully wiped mosquitoes totally out. This isn't expected to happen in a large country like Brazil, which has land connections to even larger areas. But nothing besides the mosquitoes was damaged on the islands (as far as was noticed).

You can never be really sure, but this strikes me more like the way the US eliminated screwflies than like anything else. I'd be surprised if there were any problems.

As for the "killer bees", IIUC they are becoming less viscious over time, as they inbreed with the local populations. Which causes me to wonder, "Do they suffer from the colony collapse disease?", if not, they may be a net benefit after being a short term disaster.
