I have a policy on that.....I ONLY do it to ridiculous looking rice. Never to domestics, unless they're riced-out also. Ricey rice just chaps my hide. They can laugh about the Bonneville they killed while they're signing their tickets. The last one I did was a VR6 Jetta, riced out with a wing. Front radar was bleeping pretty strong, we were doing 25 in a 25, so I gunned it when we were side by side. Took 2 tries, then he gunned it and kept going. He got pulled over 4 blocks up, probably a 45 in a 25.
He looked pissed.
