It would be the reasonable thing to do. The problem I see is when the "altered" car crashes into a stock one onthe road. The un-altered car's owner might sue on the grounds that there no proper controls on the modified car's systems to safeguard from such errors.
There is technology readily available in high end cars that will make them automatically brake if they detect they are going to hit something. If someone rear-ends me in a new car, it is unreasonable for me to sue the manufacturer because they didn't include this technology. Is this situation really any different?
