Nobody cares if you go faster or slower, just stop playing passing-lane blocker, goody tooshoes cruise control only (except when I want to slam my brakes to piss people off)
I tailgate sometimes, but only to make a point to those that are impeding the flow of traffic. I don’t do it out of habit.
I merge like it is supposed to be done, I get my speed up on the ramp, long before I can see the traffic I have to merge into. By the time I get to the end of the ramp, I have matched or exceeded the speed of the traffic, and jump right in.
Personally I hate it when I’m rolling along in the left lane and some “nice guy” cuts me off to let in some slow driver who can’t merge correctly. I guess in some cases, being considerate to one driver has unintended consequences.
