Coming to work I pulled up on a older (mid 90's gt). I motioned for him to go, and then I took off. Buslengths. I thought he wasn't racing. Then I slowed down and waited for him to catch up. I motioned again, and this time, I still I put a few (3+) buslengths on him from 65 to 120, but I think he was actually trying.....hard to tell........... Guy gave me the thumbs up after, and was very impressed, so I think he was accelerating...and a bit suprised to be pulled on that hard.
