It would have been cooler if you only adjust the speed and not use instant stopping on the precisions, those looked silly.
Anyways I was experimenting with this as well when I was playing SAMP, this speedboost can be funny sometimes. And just like the recent VC gravity mod collab, I would like to see an infy collab similar to this but with somewhat controlled environment (like the speed of the car is maximized at 1,5x or 2x of the normal speed). I'm sure this would open a lot of new possibilities as well. Hopefully someday we will see
