Arizona does have dust storms, enough so the state has tips about dust storm driving. Also impressive thunderstorms which can limit visibility at least as much as snow - you get spray from everything including the rain bouncing back off of surfaces. The world will find out pretty quick if Waymo engineers assumed the weather would always be nice.

There was discussion about sensors a few days ago. It's pretty common for manufacturers to put sensors up in the center of the windshield, behind the rear view mirror. This is my wife's Mercedes:

They are in the area covered by wipers, and in this case, that sensor area is heated too. The car does have parking sensors in the bumper that get snow-clogged in heavy snow. If you are going 19mph or less, you have to switch off the parking sensors.

The automation this car does have works very well. I've driven lots of cars where you couldn't trust the cruise control to stay within 5mph of the chosen speed, and an outside temperature readout was only accurate by sheer chance. This car has automatic wipers, headlights, climate control and cruise control, all 100% reliable. After a very short time, I just trusted the car to take car of stuff. But for some reason, the traction control is terrible.

What amazes me is that they didn't do wires first.

My guess is that autonomous vehicles will have some weather monitoring ability and decide that they just can't handle certain conditions. Also at some point, the cars will pay attention when the governor or other official declares a snow emergency and travel ban. Today I can just ignore that but the car won't let me in the future. I can see the car knowing there are 48000 miles on the tires and the manufacturer's traction data, and just not moving.

Weather forecasting isn't really good enough for this to go perfectly. Someone will have to consider what the car should do if it's on the road and encounters a sudden weather change.
