Flip side: what if a driver said, "I will be working from home on days that it's too cold for my car to start" or, "I will be working from home on days when my street is under construction."

It seems to me that it's something for you to work out directly with your employers. If you have alternate means to get to work, then they may ask that you avail yourself of that. If you don't, then maybe they'll ask that you take transit. On the other hand, maybe that will give you a 2 hour commute and they'll take mercy on you. Or not.

In short, it's all particular to your situation, I think.
