Kind of cool at a drag strip, race track or some car show exhibition...
But on a personal vehicle?
Personally, I think it is not worth the expense or potential to get into trouble with something like that. Where could you use such a thing and not get in trouble? Your own driveway? The neighbors will think you might be a little off the rails...
Even if the device is not illegal by itself, I would think life would get complicated with tickets and court dates. If anyone ever got hurt or property got damaged... You might get sued. If an insurance company found out about its use, they may decide to make you uninsurable.
I don't like flaming (pun intended) other people's ideas for customizations or mods. But this is one idea that just has me scratching my head on why anyone (other than someone with a show car) would think this is a great idea...
Certainly your choice, but I can't say I go along with the concept being a good one. Nothing I would ever think of pouring money and time into doing. I guess I am not that much of a risk taker.
Best of luck! Stay out of trouble and stay safe.
Let us know how it works out.
Cheers!
