Yeah but this is dangerous. Like people have no idea how brutal this force will be, and even if it can be cutoff, picture this: 0-100 mph will be in the high 2 second range. So some idiot hits the button, and 3 seconds later he's doing exponential speed. Not only that, but what happens if the person hits the brake when these boosters are firing to stop from hitting something? Even if they cutoff immediately after that, it still is wayyy more momentum to stop.
And by cheating, I meant like where it cannot be used frequently. Not only that, but MotorMatchup has a SpaceX Roadster visualizer (

The acceleration after is not proportional to the acceleration just prior, so it looks like it's extremely slow. This in turns makes the car look like it's trying to be something it is not. Boosters are for rockets, NOT cars please. I like cars that have non piggybacked speed
