I've got a 2020 P700 and would like to consider letting my grandkids drive it around the yard a bit. Trouble is, they can easily get in over their head in "stock" form. I'd like to do something to limit its speed, but am not sure what the possibilities might be. Obviously, I could leave the driver's seat belt unbuckled, but that's just stupid from a safety standpoint (I want them buckled in). Does anyone have any other ideas on what could be done (and easily undone) to limit the speed/acceleration? Given the fuel injection, I don't think I can do the same types of things that I could with a carb, but perhaps a throttle stop or something? I'm open to suggestions.
