I don't understand a word of the technical stuff but is this the future of slot racing?

Hi there! It certainly was feasible, and worked! But after a while it was difficult to stay focused!
With prolonged training, it would be possible to directly control the speed as you drive the track, but because this was used by the general public, there wasn't much time for them to have much training, so we put a speed limit on the cars - nothing as distracting your focus as getting annoyed having to pick up the cars.... again! ;-)
