There are a couple of problems with taking advantage of this perceived “kindness” by drivers in situations like this. First...as a cyclist...I’ve always felt that I’m safer behind cars than I am in front of them. There are times that I’ve had the right of way on the bike and I take it. Only to have the car turn in behind me...and then not be able to pass me for one reason or another (narrow road, oncoming traffic, etc.)...and the driver then becomes upset because I’m blocking him/her. Secondly, when cyclists recognize this “kindness” I feel like it legitimizes and propagates it. The yielding driver, and possibly others at the intersection will see it and continue to do it.
