I'm saying that the limits of self-driving cars will be an excuse to force us to behave the way the authorities want us to behave. For better or worse.
Winter here is 4 to 5 months out of the year. When it snows, everyone goes about their day normally, just at a slower pace. The authorities have no problem with that, and having drivers on the road does not affect plowing in any meaningful manner.
I'm not sure why you are trying to justify such a large shortcoming - for most people having your car be randomly unusable for 1/3 of the year would be a big deal.
