So, sometimes it's fun to floor it when you're at a light and it turns green. But not at the expense of the finish of the car behind me. This thought has crossed my mind a few times but I'm only now remembering to ask it. When I floor it at a light, do I kick up grit and pebbles and spit it at the car behind me? Has anyone been behind the S during an "acceleration test" to answer firsthand? This is probably more an issue for the P85s than the P85Ds.
