Yeah I agree it sucks there arent bike lanes in a lot of towns. In most places it would be absolutely fine to use the side walk, but the center of university towns are congested pedestrian walkways. For the same reason you don't want to be out on the road on your E-bike, people walking to class don't want to share the way with fast moving E-bikes. This has never been a problem with regular bikes because people don't typically sprint them through the middle of campus.
