Aggressive random braking is also a safety issue.

Yep, this is the thing that worries me the most on some of these systems right now. They are going to get rear-ended a lot for the next few years, IMO.

Rear ends have basically no fatality rate though. They do have material costs but if optimizing for no loss of human life it sounds more appealing.

These kind of tradeoffs were things every self-driving car software developer KNEW they were going to have to deal with - the most extreme being the one where the software has to decide who to kill and who to save:

And rules out use on snowy roads.

Why? Brakes works fine on snowy roads. Distances can be adjusted for snowy roads. It happens every winter where it snows a lot. I don't see a problem.

Not sudden random braking, no. The most important advice for driving on slippery surfaces is to avoid sudden braking, and in general to be careful when you brake.

That'll teach people to keep their damn distances!
