Gonna pick on this one statement. Basic cars, yes, but not mildly modded ones. My V8 RX7 pulled 1.2 G laterally without big wings and underbody ground effect tunnels, on street tires.
Exception not the rule, true, but streetable cars can be made to do it with little investment.
While pulling a g of braking? Not a chance. I expect it will be very hard to find a place where the algorithm does not go to full braking instantly...got rid of the inertia whatever happens.
And not really relevant in any case. We are talking minivans and SUVs and conventional four door sedans.
You may (or maybe not) remember that at one time elevators had dedicated human operators too.
The first elevator was made in 1853. I suppose by 2183 autonomous vehicles will be as safe and common as an elevator and have almost totally replaced human driven vehicles.
Where I live this winter has been very challenging. Lots of snow and icy roads, and of course lots of accidents!
I wonder how driverless vehicles will operate on black ice. Almost all the side streets and alleys have been treacherous. Driverless cars in the winter? I'm curious how that will work.
Sure. Race cars'll do 2-4g laterally while pulling a G of braking. And with modern anti-lock braking slowing at the threshold with sticky rubber (it's really all about the tires), it's not that hard to do over 1 G of decal and lateral at the same time in a street car. Go to any autocross track and you'll see daily drivers doing it all the time.
As for the minivan comment, you did NOT specify, you simply said a car will break loose past 1G and that's simply not true in all cases.

On ice, a driverless "smart" car will probably pull over and say, "heck, No! I'll wait till it melts."
But seriously, it will probably creep at a snail's pace, selectively seeking paths of greatest traction.

You should be able to program a car to drive much better than the average driver on black ice. Software isn't going to cluelessly jam on the brakes after entering a corner or a steeper downhill stretch too fast.
A self-driving car would be receiving all kinds of telemetry information telling it there was high black ice risk. 32F. 100% relative humidity. Yep. Look at any video clip in the south taken during a freezing rain event. Poorly trained humans have kind of proven they aren't particularly competent at it.
There are no production driverless vehicles. Only prototypes.
Let's see 'em navigate a country road in a snowstorm (like I did the other day) first.
Exactly. What happens when the snow dust freezes over the camera or rader lense ? Or the road is fully covered in snow and there 4" deep ruts that the car now has to navigate ?
My dad has a new Grand Cherokee and experience the snow dust thing first hand. It disabled the "auto" braking feature.
I know the technology for driverless vehicles is just now really developing , so I'm sure they will get things worked out. I'm still not understanding the big push for it. Then again, I don't live in a large city and generally when I drive (other then my daily commute) I am towing snowmobiles, or ATV's.
