Because certain types of technical advancement requires an element of devaluing people. "Calculator" used to be a job performed exclusively by humans. Moving to mechanical & digital calculators didn't only require gains in efficiency, but also a recognition that this was a job humans were simply worse at than machines, so it was irresponsible to task a human with it. Similarly self-driving cars can't simply be a nice…

Promoting the tech and respecting people are not mutually exclusive. I'm not arguing that we should endanger people and my comment is not about this one instance. It's about a general attitude of devaluing people. Where do you think that road leads? When Uber vehicles were found to have run red lights a couple of weeks ago, Uber's response was that these were human operated and served as an example of why they must r…

What do you even mean by "devaluing"? Of course a more error prone, dangerous and expensive driver has less value.

Is pointing this out somehow wrong? I think not pointing it out devalues human life.

The road of getting rid of fallible humans from boring automatable jobs leads to Utopia, and I reject your notion that this is somehow inherently different from e.g automation in agriculture or computing

This is great video to study on many levels beyond self-driving car. Some observations: * The car behind didn't show turn signal so probably driver wasn't paying attention. * A small car escaping with not too much damage while SUV rolls over many times * From physics point of view, the car behind produced almost perfect torque that started horizontal spin on SUV * Collisions with barrier at high speed can produce lot…

The biggest thing I noticed was just how easily SUV's flip over. This has been a problem forever I'm just surprised that regulators don't take more notice of it. Rollovers are far more likely to result in injury or death. Most cars just don't flip, all the traction their tires have is simply not enough to do it on flat ground. Yeah anything could flip over once you go off the road but the SUV in this looks like a rol…

That also depends on the momentum (weight ratio, impact speed angle, etc.) The lesser the weight, the worst off during impact - we've seen that too often in NHTSA crash tests.

>What do you even mean by "devaluing"?

I've been clear about my meaning. Can't simplify it any further.

>Because certain types of technical advancement requires an element of devaluing people

That's your quote. What did you mean?

>Of course a more error prone, dangerous and expensive driver has less value.

There's a difference between preferring tech to do the driving and saying the human has "less value". You don't see that?

In any case, a hostile regard for human fallibility that approaches promotion of the dispensability of humans isn't a good thing.

This is exactly how Elon described the system. Forward looking radar now bounces radar under car in front, getting back location of 2nd car in front, and responding to sudden braking etc.

wow - didn't realise this is a thing. Colour me impressed.

I thought this an interesting video when Elon retweeted it. Basically the car is responding faster than the people do and keeping things from escalating. That said, having been on 101 when the cars in front start dancing like that I have to say my biggest worry isn't stopping in time its having someone behind me not stop.

That's why I usually break fast initially and check the rearview; extend the braking distance to allow extra room for the person behind if they are too close.

That's a good habit - however we don't know in this video if the SUV that got flipped over was braking suddenly, which can also cause collision without the rear car's anticipation (e.g. the rear car driver might be checking the right lane right before passing on the right etc. and missed that information for a split of a second right before collision.)

What puzzles me here is that the SUV flips over after being hit in the right-rear corner by a relatively small car and bumping into the side barrier. Flipping over in a case like this looks more likely to happen to an SUV than a lower-centered car, and makes me question the safety of SUVs.

This is a commonly known problem of SUVs, their center of gravity is a lot higher so they're a lot easier to flip over. That's why I'm puzzled by people who buy urban SUVs, that is, jeep-like cars that they never intend to use off-road.

Ride height, more cabin space for kids, some use for four wheel drive if you live in a climate with snow/ice, and/or personal preference?

I currently drive a civic so am just guessing...

Transporting a family takes room. Rear facing car seats don't necessarily fit into smaller cars.

Large sedans and station wagons are valid alternatives; SUVs are similarly or higher-priced than safer options.

Height is the big advantage of SUV's and minivans. Kids stay in carseats much longer now and the seats can be quite bulky. It's a lot easier to load them into something with some height.
