V2V is coming whether it's a good idea or not, but on the plus side it will produce a lot of data which would be useful on a HUD. It could tell you which vehicles are braking even when the sun is in your eyes and you can't see their lights, for example. It could also guide you to one side of the lane or the other (or to another lane entirely) in order to dodge a pothole or other road obstacle that you can't possibly see, well ahead of time. So yeah, there's a whole lot of data coming which could well be useful for the driver. Night driving is another place where the HUD could be amazingly useful, alerting you of invisible obstacles outside the sweep of the headlights.

No, there is substantial debate on this subject still. There are two camps: red light does not affect your night vision, and blue light helps you stay awake. Actually, night vision is regularly impaired while driving anyway, so that's a dumb argument. Get a car with good headlights, use them.

A problem that solves itself if you permit anyone to perform as a taxi.

That actually seems useful. Could better be served by handicapped-specific public mobility services, however.

That must be nice. No taxi I've ever been in has been clean. Some have been not too nasty.

False everywhere in the world.

Basically worthless

Everyone should have these based on mileage

A scam to produce revenues

Study shows that when you misuse HUD, it can distract drivers.

But if you're showing them an alert about something they're clearly not aware of, then are you making them more or less aware of their surroundings?

If they don't have to look down to see the next navigation instruction, are you making them more or less aware of their surroundings?

Bullshit story is bullshit. Welcome to Slashdot!

I seriously don't care if polls are in the main story stream. I seriously think that the people complaining about it must have something wrong with them. Just skip over it. Whogivesashit.

Also, while I'm ranting, Slashdot polls have always been lame. So what if this one is also lame?

The one valid complaint about these polls... CowboyNeal Option

It will also breed further contempt for Java. Has Oracle thought this one thr- OK, sorry, stupid question

Is there any doubt that someone led them on? And once they discovered the magnitude of their idiocy, they had no choice but to ride it out lest they reveal how easily led they are?

That'd be fine, but we're not talking about doing that in this country yet. That's the only kind of nuclear power I would promote. Show me an effort to fix that in the USA and I'll get behind it. Also, there is still some waste left over from that. I'm going to have to see some evidence that we'll handle that responsibly. So far, nope.

Yes. They add a couple of hundred dollars to the price of the average car and they make the world a better place; unburned hydrocarbons are the most foul emission which automobiles make. You might also be interested in knowing that we averted the ozone depletion crisis by banning CFCs. Meanwhile, the O2 sensor that came along with those catalysts actually lets you make more power while burning less fuel.

Give it time. It's got thousands of years, even if we stop using it today.

The user is slowing down and doing it right when you're there. When you're elsewhere, they do it fast and they do it wrong. Tell them to slow down, close the case

You forgot to thank Jesus, and the academy.

The roman roads wouldn't last for generations without maintenance... and their maintenance costs helped bankrupt the empire. Hilariously, today road maintenance companies with Italian names are being drug through court for the offensively bad job they did around northern California. Less hilariously, the taxpayer is currently paying for some of those "repairs" to be repaired again. Last night I drove over the parts they're about to patch between Lakeport and Kelseyville on the CA 29, and it's a bunch of short disconnected sections so it'll be like speed bumps again in short order. Some of them are 80% of the width of the lane, to save a few bucks they're creating uneven lanes. Lake County CA has become a bedroom community for the Bay Area, and people are actually commuting now into there from parts beyond like Ukiah — if you're going into the East Bay, as bad as traffic is around the central BA and where the 101 passes through it, it may well make sense to go over St. Helena. Which, by the way, is also under maintenance right now, because California. A commuter coming from Ukiah might well face over an hour of delays alone (let alone secondary effects) if they don't know which back roads to take. I guess I forgot to mention the roundabout they're building at the intersection of CA 20 and CA 29.

I did mention the 101, though, which is still horrible. It's easily one of the worst freeways in the USA. It's the road I bring up any time anyone suggests building roadways out of concrete, or anything similar.

On the other hand, the Romans had very different standards. They didn't expect to carry multiple lanes of traffic at 80 miles per

Your comment seemed so intelligent until we found out how little you value your brain.

You can get a pretty good gun for $200 and a really good gun for $500 these days. You can get a CNC'd 1911 for that now... or something more modern :) And yet a 3d printed gun will literally never be as good, because it will never output forged stock. (Perhaps one day we will develop a universal assembler, and that will be better than either of course.)
