Look, "autopilot" works on highways, where there is a median. Everything goes the same direction, and there is a minimal amount of clutter.

Its about as easy as driving gets. This is why a level 2 "autopilot" can parade around the place as something that is both innovate and safe.

None of the data compares what happens at junctions, which is where the majority of crashes happen.

It cannot work in suburban sprawl, It can't cope with poor weather, it can only drive on highways.

Not sure why you state this. I've used autopilot in a Model 3 on city streets and suburbs, it works pretty great.

Similarly, I have used autopilot in rain so bad that I was scared to drive. It performed perfectly and was much less stressful for me.

I was fully engaged and ready to take over, but never needed to.

I'll echo that. Heavy rain, I could barely see the lines, but the car seemed to find them just fine and was driving straight and smooth.

Until traffic on the other side of the median barrier hit a big deep puddle, absolutely covering my car with a thick sheet of water. Autopilot immediately started screaming at me to take control. I already had my hands on the wheel, but it still scared me because I couldn't see either! After the water washed a way in a couple seconds, I was able to re-enable AP and keep going.
