In my short experience with an AP1 Model X on an extended test drive, the rain sensing wipers are pretty bad on AP1 cars. They do seem to at least turn on when it's raining, but the speed and frequency of them seems to be really random.
The AP1 rain sensor is no worse or better than every other car I've ever had with wiper sensors. I do feel the 2 position sensitivity a little bit backward though. That takes it back to the first car I had with rain sensors, a 2001 BMW 7 series. The last car with rain sensors had 6-8 sensitivity settings if i remember right.
