Couple of months down the road, this car has a hiccup, stops in flight, mis-levels, passenger trips, breaks a bone, sues for disability, lawyer finds out the controller burned, also finds out 2 major companies including the manufacture wanted to mod, you and the owner pay a lot of money to the passenger.

Smaller companies love to bash the big boys for trying to "take advantage" of customers but this is what the majors have to think about. I have had multiple instances of this type of situation happening. One of them seriously injured a passenger which resulted in a huge lawsuit. If you don't know what you are doing please don't put the public at risk, it's bad for the whole industry.
