I've had food thrown at me by motorists when I'm in dedicated bike lanes.
I've been buzzed by trucks and buses while in bike lanes.
I see cars regularly use the bike lane outside my house to make aggressive passes of slower auto traffic.
Pedestrians have been killed crossing the streets near my house. All by cars, not bicycles.
Cars regularly kill animals. And not just squirrels, but raptors and fox and other predators we don't want to lose.
And on and on. We all have our anecdotes. The answer is dedicated infrastructure for a range of transportation.
You don't live in Boston, I see.
To the other responder, I agree that cars are frequently assholes to cyclists, but how is that relevant to cyclists abusing pedestrians?
