Believe it or not, but different things require different types of legislation. Not everything can have the exact same type of rules.
Cars cannot be concealed and brought into places to murder people, or kill people from a few hundred meters away, but they can cause fatal injuries so things like seat belts and air bags became mandatory. Stricter crash test standards were invented. New materials were used, and new technologies were put in place to prevent injuries as well. Car seat regulations and a plethora of other regulations were invented.
There are speed limits and a license is required to use a vehicle in public. If you abuse the car, you can have your license revoked and driving privileges suspended. To drive a vehicle you are also entered into a database with all your information stored in it. What type of car you drive, what year, etc. is all entered into the system.
Different regulations for different things! What a novel idea!
