Question: Why don't you guys just go to a drag strip and see what your cars run? Entry is usually about 20 bucks for unlimited runs. It's really fun to do at least once.
Track is 3 hours each way depending on traffic, $40 and you're lucky to get 3-4 runs if you're there for 6 hours on a Saturday. They have two week nights where you can get a bunch of runs in for $20 but the prep is minimal and it means leaving work early, which never works out for me.
So that's $40 and a full day commitment for a few timeslips. Last time I was there I was with Dutch and it took me 2+ hours just to get through tech inspection.
Contrast that with the highway which requires $0, essentially no time commitment, and unlimited runs. Also allows performance measurement from a roll, so doesn't require me to put slicks on the car to use the power, etc.
