Can someone who's taken the new MTA Select Bus Service busses comment on whether they are smoother than regular busses? I took an MTA bus today for the first time in a long while and it was uncomfortably bumpy.
I haven't taken them very often, but I have had a couple really great experiences with the M15 1st/2nd Ave SBS. Due to cascading traffic lights, efficient boarding, and wide spacing between stops, it's almost as nice as taking the subway.
