My B&W speakers I bought in the 1980s are still working without worrying about when a cloud service will stop. Only had to replace one tweeter speaker when a dog's tennis ball broke the cone.
Meanwhile my Beermkr is useless junk now because the cloud servers have gone away.
Why do you think that will happen? The Waymo vehicles are all-wheel drive, and I think you can expect them to have good tires, probably even snow tires.
Lack of any visible lane markings during heavy snow storms is one reason. How well do those vehicles pick up the road edge markers on posts? Hope the automated vehicles will be kept off the roads in heavy snow.
