"Level 4 - High Automation

A steering wheel and pedals remain, but no human input or oversight is required except under select conditions defined by factors such as road type or geographic area (like poor weather or other unusual environments). The driver might manage all driving duties on surface streets then become a passenger as the car enters a highway. Hyundai’s NEXO is currently being tested as a Level 4 car."

I wonder how an autonomous car will deal with a human vehicle it decides to pass which then speeds up. Will it reach a point where it flags it (because it will never speed) and then drops back behind them? How long does it take to abort while holding up the impatient human drivers behind it? Also wondering how well it will work when motorways begin to get busy during peak times. Does it try to lane change constantly based on flow of lanes or just sit in its destination lane? I doubt their full potential will be realised until the majority of cars are autonomous.

It would be funny for cars to self-learn and end up with our lame habits that when there is full saturation they are driving no better!

I wonder how an autonomous car will deal with a human who speeds up when it tries to pass, and then another following human also speeds up so it can't get back into the lane, and the lane starts to narrow, and the car does a quick check on the blocking vehicle and sees that it can easily outpace it, and the only way to get safely past before it hits the oncoming car in the distance is to accelerate 50 km/h faster than the speed limit.

or more likely (just like a ‘safe’ human driver) just keeps slowing down until a spot clears in the original lane?

Eh? It will 100% depend on the algorithm written into the software!

More importantly, if you have something a group of people want badly, and they chase you to kidnap your child for example ... i know what I'd do in my twin turbo V8 .... yeah baby.

But I am guessing the robot car will just sit there and say hey take the kid, she's all yours.

(PS much easier if the RUssians want you, they'll just hack it over wifi)

Some might say that won't happen. Oh, flash floods, earthquakes, some kind of medical or other emergency, etc ... I know what I'd do. The robot will say ... yeah I'll just sit here and let the fly over bridge collapse on me - there are too much stuff going on around me, syntax error.

As long as my body is able, Ima control my own car as much as possible thank you very much.

Loving all the hilarious hypotheticals. You're sounding like Mike Hosking! Keep them coming!

Meanwhile we get closer and closer to bad drivers like yourselves being outnumbered on the road by these superior self-driving cars :)

So the only time a person will get to drive will be in difficult conditions. Sounds like a receipe for disaster to me.

and stuff that I can't find on youtube does not mean they don't happen, as I have known of many first hand attempted abduction and carjacking, for example

yeah i know, all these are just hypotheticals, coz it's never happened here

I don't get the banter with hypotheticals. A CPU will stop, steer, avoid better than a human. It has a 3/4 reaction time advantage for a start. Off course in the hypotheticals, a CPU car will get done, dented, damaged, etc, but it will fare better than a human.

Of course they do. The software is generically called ESP / electronic stability program. All my cars have it. All my rental cars have it.

I do wish my cars have collision avoidance systems. ANd I certainly wish all cars that pass me on my bicycle have it. Every time.

Why dont these cars that are being tested on roads have it? Clearly the Uber one didnt, so the others have it? There is no need to code for 500,000 scenarios, but its about the all self drive cars had proper detection and avoidance software IN USE. Going by the Uber example, its great it takes you from A to B. And knocks over whatever is in its way

So a hypothetical one-off situation where there's no way a self-driving car could react in the way it would need to, and a human could, is FAR more important than improving the overall driving experience, reducing travel times, road deaths etc? The needs of the few outweigh the needs of the many?

A self-driving car can't beat a carjacker, so ban them all! To hell with any of the benefits.

Definitely Mike Hosking thinking.
