Hey AC? Who are you that you post off-topic political stuff on literally every forum I read no matter what is being discussed? Why do you do it? Is it entertaining? We get it. You love Conservatism. Do you think you maybe need a hobby? Like hacky sack, or model airplanes?

They're not as safe as people driving cars, which currently achieve 1.25 deaths per 100 million vehicle miles. They won't be that safe for a long time, and they need to be a lot safer, since we won't find them nearly as forgivable.

Microwave them.

Good idea. I'll try it.

Hey everybody. I make stuff (educational games mostly) and put it on the Internet and I don't charge anything for that stuff. I don't run ads on my websites. I use HTML5 to make my games, because I believe in open web standards, and I want my games to keep working forever.
Two of my games broke.
I can't add the click callback fix, because both games don't even use the mouse (keyboard only), and load with the game in a centered div. Neither game is fixable, unless I tell my users to click, for no reason, other than Google is stupid.
I don't like ads either, but I think everybody should follow the rules.

No, but if I've already worked one cheek off my ass to get my $16 an hour, and I'm working the other cheek off to stay where I'm at, I'd be tempted to say fsck it and go flip burgers for $15.

Might I suggest you check out my CC-Licensed book of 4th grade mathematical programming lessons in Scratch:

I teach 4th grade, and the book follows the math curriculum as it progresses during the school year. In my experience, a mathematically precocious 8-year-old will be able to grasp much of it.

I'm the Google site admin for my elementary school where I teach 4th grade. That makes me responsible for maintaining my class's passwords, as well as the passwords of five other classes - that's nearly 200 4th and 5th grade kids with a fairly transient population. The Google username scheme is non-negotiable because of security issues and committee decision making and consists of the first three letters (if there are three) of the first name, the first three (if there are three) letters of the last name, and the first three digits of their numerical student ID (which they do not know). The password scheme I came up with has the kids choosing two words from a table of common four-letter words. They put those words together with the last digit of their year of birth. They must use this username and password to even get into the Chromebook for most purposes (anything that involves document editing). The classroom app that Google unveiled this Fall is awesome. It's simple and perfect for what it does. I have the kids write their username and passwords down on a post-it. Secure enough. 90% of them have no problem remembering it, but some of them come with their shoes on the wrong feet, so I've been satisfied. I just set the other kids passwords manually after making them write it neatly on a post-it note and usually finding their error. The only third-party thing I use is Scratch, and I make my kids manage their own credentials (I offer a post-it). Scratch is amazing and my kids are motivated to manage it themselves. Scratch, by the way, could be the best thing to happen to math in 200 years of education if people would stop teaching math and start doing math. [Brag warning] Check these out, and tell me you wouldn't have died to build them in 4th grade: http://goo.gl/pHF6Hd We do one every week now.

I went to chicago for the weekend #survived..

Takes on a whole new meaning here.

Yet again the human race proves it has zero business messing with nature. Seriously, who is surprised by this?

I wouldn't say they're not concerned with security.. but rather, they're probably the most targeted.

I can see this reducing emissions, when I consider the assumption that whoever is leading the train does not drive like a bloody idiot. In a modern car, even with today's technology, most of us tend to drive as fast as we can get away with. 65-70 miles per hour is common in my area, but mileage increases significantly if you forget about trying to get to your destination a whole three minutes faster than it would be (on average) if you just relax and drive 55.

Personally, I dislike setting my cruise at 55 and getting there "when I get there". It's more fun to step on the throttle a tad, turn up the tunes, etc. But it's rough on the fuel tank, so I don't.
If I could tag along with one of these trains for my commute, or better yet.. even for a while on long trips, read a book, enjoy a cup of coffee, enjoy the scenery - anything but focus on driving- I don't believe I'd care if the train were moving 45 or 55 miles per hour. I'm not driving.

That said, my major concern is this- I live in an area where a typical winter day of driving is fraught with icy, snowy, wet roads. I don't believe any car would be safe following a lead vehicle at 10 feet, let alone 10 meters, in those conditions.

that said.. this could be some devastating psychological warfare goodness.
If an army is too busy scratching to shoot, everybody wins.
