I've gotten thumbs up from everyone I've passed. Even the kids look on with amazement when I pass them by. I think the only ones upset are the car drivers because I get to the traffic light as they're sitting at it and they realize I didn't use a drop of gasoline to do it.
I also beat 95% of the car drivers off the line at the traffic light which is really funny. Then they pass me with their engines revving as fast as possible burning even more of their fuel.
My only regret is that I didn't build my e-bike sooner.
