Yeah that shit's pretty bad in SF
Cyclists act like the rules of the road don't apply to them but freak the #### out if they perceive anyone getting too close for comfort. There's a ton of them out here so they have too many rights if you ask me. They even sectioned off huge parts of Market St (the main street in downtown SF) for bike lanes. And those "Citibike" hubs are ####ing everywhere.
SF also has some of the worst drivers of any major city and I'm a native so I know this better than anyone. It's that deadly combination of entitlement and the tendency to be easily distracted.
