Tesla

It's pretty good. I think they're onto something here.

It navigated some annoying traffic very well, took a right on red perfectly, twice. Did a roundabout just fine twice.

The bad bits:

Speed limits are odd, if it can't figure it out it drops way low. (I have heard if you turn off automatic speed offset it fixes that)

There is one long turn lane it popped into halfway down instead of immediately, as would be preferred. It could catch another driver unaware.

It goes way too fast into the roundabout. Just an unpleasant deceleration, but it's not unsafe.

Auto parking was cool, but slow.
