If it will shovel its way out of my driveway, I'm in.
I've seen multiple ottos and uber self driving cars driving during the rain so I'd trust it.
Ubers self-driving cars have LIDAR. Tesla autopilot is fully based on view from cameras that can be obstructed.
LiDAR doesn't work well in rain and it's just a ray of infrared laser light scanning surroundings, so it can be obstructed the same way as cameras; radar is what you want. But NVidia uses just 3 normal cameras and deep learning to drive in rain/snow/night and it seems to be working for them.
If anyone isn't aware: While most companies use LIDAR, Tesla uses radar
All of them use both, and in multiple instances of each. So they might have two front LiDARs, two side LiDARs, one rear LiDAR, one front and one rear radar, ultrasonic sensors etc. and then perform a sensor fusion to map car's surroundings.
