So speeding without the engine on is ok?
OK, I will admit that the
only speeding ticket I got was in a vehicle with NO engine.......
In that case, the speed preventer sticker wouldn't have helped me anyways.
I also remember that it always seemed like old cars had "55" in orange or red. I wonder if that had to do with any legislations from the 1970s oil embargo?
Some sort of visual indicator just seems like a good idea.
I have no idea how to do it, but Piwoslaw's mention of an audio indicator of speed is really interesting. Perhaps a speed sensor could connect to the "you left your lights on" chime that most cars make?
The only way to turn the annoying sound off would be to slow down! How's that for motivation?
