Of course most of the actual R/T at the tree is the car. Or should be. A normal human can react in about .15 seconds or so, the .350 is/should be the car ... but the part that usually messes up the R/T is the person, not the car
I guess I could check for the average of R/Ts from the weekend, I would imagine they are well beyond .7 oder .8 ... (even without counting the spectator runs!)
