Couple roll races on the interstate on my way home with a nice little sti...all from 75-80 mph...tried to get a low speed roll but he wouldn't go below 50...he took the hit 2 times and jumped a half car or so...i finally gave him wot on the third time right as he hit.... pulled on him and shut it down....with 14psi and pump gas....we both took the same exit and I signaled right hoping he would want some low speed hits but no cigar and pulled an exit stage left...
