#BikeNite A8. As someone who has just gotten back to cycling, the complaints I have heard (from driver of vehicle I am in)
"Why are they in the road? They're in the way! Roads are for cars!" (usually, this is 2 or more folks, typically on Saturday morning, sometimes a peloton - in California, cars are supposed to give way anyway.)
"Why don't cyclists follow traffic rules?!" (Usually when someone just ran a stop sign -- sometimes valid, sometimes not).
"Those cyclists think they're in such great shape, cycling in their spandex, hmmmph" (Interpretation: I'm SO out of shape from driving my car everywhere, I am very jealous of cyclists, I am angry now)
