VaSteve: I used the little white magnetic switches you can find at Radio Shack with double sided tape to mount them near the gas pedal, and then used small magnets attached to the gas pedal.
Ted: I agree, les is more, and I don't really focus much on the dash when it get's busy. I really like the ability to review the video, however, and the dash lights really give me some valuable feedback. Eventually, I'll probably hook up a datalogger and pay the money for the sexy software that you can overlay onto the video. For now, I'm trying to keep the budget focused on safety and performance.
