The tesla system is exciting and dangerous, because it does identify many things in the environment, but it's extremely unsafe because on city driving it will not make the right choice most of the time. On the freeway it does much better, but then that's a more restricted environment.

I have an older tesla S with the pre-ai so called autopilot. It has one camera in the front and a radar and the system detects a few things like speed limit signs. The main extent of what it can do is follow the current lane pretty wall, even when it curves, slows down if it comes up to a car going slower than its preset speed. The good thing is it works on any road. It does a shockingly good job.

The later systems with onboard special processors are like a crazy beginning driver to has way too much confidence and drives in dangerous situations willy nilly. There are many other people who have explored it and written long posts. It's not safe. You can try to use it be you have to be constantly paying extreme attention. It's like watching your kid drive the first time. I know you should be watching the stupid ai all the time, but it's far from being safe.
