it makes perfect sense. i tend to stay away from my road bike when i have to ride in traffic just because of that disconnected feeling. my mind wanders on a road bike a lot moreso than when i'm riding my fixie. it's like, riding a fixed gear forces you to be fully engaged in riding the bike. it feels more natural to slow down by resisting with your legs than by pulling a brake.

everything you said should make perfect sense to anyone who's ever ridden a fixed gear, and then gone back to a bike that coasts.
