Tell him to kiss your ass! He needs an advantage to beat a 7000 lb. truck? I'd tell him the race would be from a dig or none at all. Unfortunately he will probably easily beat you from a roll, his power is instant.
Well he won't race me from 0-100 only from a 20mph roll. So we will see how I do. I've never raced from a roll should I still put it in 4hi.
