This is one of those perpetual arguments where both sides have some valid points and both sides have their "fuck-ups" too.
IE: Bikes should respect cars & cars should give bikes a little space right? But what about the cars that shift lanes or crowd bikes off roads? Then there are "bike folks" who ride in a lane like a car, but when it's a traffic signal they blow through it or a stop sign.
I try to leave them room and if they look like a possible accident about to happen, I get the hell away from them. Somethings are just plain ignorance too - kids bopping out from driveways or between parked cars.
Again it boils down to alot of talk and no-one taking the initiative to educate all parties.
