> Contrast this with the Minneapolis bus system, where you could time the busses at stops within 2 minutes in the central city, even while a foot of snow covered the ground. Both systems used essentially the same equipment -- same models and manufacturers.

Aghh, I hate the Minneapolis bus system, I remember two times in the winter when the bus just didn't come, real nice when it's -8F outside. Or buses being 15 minutes late. But worse of all are the bus drivers themselves. However the Blue Line and Green Line follow the schedule much better then the buses. If your in Minneapolis your best off either driving, biking, taking LRT or catching a Lyft or Uber.
