I think dekhn may be making the same point, so no need for "Just to be pedantic." You raise an interesting factoid that many people probably haven't thought about, although it's pretty easy to intuit once you are encouraged to think about it.
No I wasn't making that point. The side-pedants talking about racing cars, those represent a tiny amount of braking activity compared to the total amount of braking activity across the world, so my statement about expecting the average velocity to go down still stands.
Also, I drift corners instead of braking, it seems to be a lot faster if you nail the tire orientation on the exit.
