Anecdotally I cycle into Cambridge almost every day. I cross three cities: Medford, Somerville and Cambridge for an approximate 20 minute commute (vs 40 by car.)

I have never had issue with cars, granted I've only been doing this for the two years (and in college I used to commute from Roxbury to Cambridge for 2 years and only had 1 freak-out with a drunk-driver, but that's another story.)

On the other hand I've seen entitled cyclists lose their shit for no reason at cars.

I feel like there's a subset of cyclists that don't understand that cars may have blind spots and freak out at drivers when there's literally nothing the driver can do about it.
