I mean let’s be frank here. The sort of people who are enthusiastic about this also aren’t going to be stopped by the law especially with the low risk of getting caught.
If I were to personally install this and use it anyways, my biggest worry would be the additional punishment if I cause an accident. Not sure exactly what the punishment is for driving a vehicle you know isn't road worthy, but I bet it aint pretty.
While the chances of getting caught are low, I wouldn't want to risk this for insurance. If you are involved in a crash for any reason I don't think they are going to cover it if you modified this stuff on purpose.
