Yeah. Hope I didn't sound critical of you for the right-hand turn issue. Sure -- it upsets a few drivers, but taking the lane is the safest course. To stay to the right invites the car to pass . . . plenty safe for the car but not the cyclist. I think we agree that's different than blowing a blind stop sign at high speed.
Speeding through a blind anything is always a bad risk. I've seen close calls when people take blind curves on MUPs too fast.
