Well, you're the one driving like a granny in a race

(if you're fuel saving on bald tires)
It invites accidents. Two people racing each other catch up, have to slow down behind you, more catch up as a result. You're creating a traffic jam behind you, can't expect no one in the group to try to take advantage of the slower moving train and force a move.
It's also why max SR.S races have more trouble imo. Matchmaking puts slow and fast drivers together to fill a room which causes extra confrontation.
Also when you get lapped and want to let someone through (not you, in general) please simply let up on the gas, don't step on the brake! Yesterday #17 put on his hazard signals, yet then braked so hard on the straight I crashed into him before I could swerve...
