Continued reaction to burning hydrogen in Minnesota:
Not sure how much worse it could be than it already is. Glad that studded tires are allowed on bicycles.
The real question is whether there’s a stud on your bicycle. Heh. Another reader:
I don’t think even 212º warm is warm enough on those minus 20º days. Some water vapor will freeze directly to the pavement, going right from gas to solid.
Quite possibly. Remember this?

So I wonder how much H2O would be produced by a typical vehicle on the highway. Are we going to see cars with little bladders attached to their tailpipes? Or would this happen?
