I think it's a good idea to clamp a car by limiting the travel of the accelerator pedal, but it can be a problem: sometimes we are faced with situations where we would need a little power .
The spring system is actually much better, I thought to make one but for lack of time it stayed like that.
The "difficult" situation that we meet most often is when re-accelerating at the exit of a very tight bend on a climb, such as we find in small mountain roads. We find ourselves downshifting much more often than usual and we go up in 2 ° what we easily went up in 3 ° before. It's downright painful to drive like that. (Asthmatic lung drive ). In the city when you drive calmly it does not change anything.
