You are right. You wrote: <<3 blocks before the intersection if you don't want to slide through it>> It sounds like road maintenance needs improvement in your city.

When it's -30 for a week you end up in a situation where road salt doesn't work and the exhaust from cars polishes intersections to an icy sheen. It's hard to protect against that.
