If the ESC can't handle the full 18v, it'll blow regardless of how you're powering the servo tester.

I was confused about the pot because it sounded like you were asking why to use a servo tester at all. I'm thinking something like a flexible pushrod from the pedal to the horn on the pot could work. That way if they jump on both pedals the cable will flex instead of braking anything off of mounts. You'll also need to "connect" it to the horn in such a way that turning the other way doesn't push the opposite pedal further out (kinda like the brakes/carb linkage on a nitro car)

How do you plan to handle reverse? Having a kid hit the brakes, then hit them again and go in reverse could give them quite the shock if they were just hoping to stay stopped.
