1) That's a bullshit statistic
2) Vehicles have uses other than killing people
3) There isn't a lobby group advocating unsafe vehicles be accessible to everybody
4) There is a concerted effort to make vehicles as safe as possible
But apart from those minor details, you hit the nail on the head.
5) You must pass a practical test and obtain a licence before you are permitted to drive a vehicle
6) Vehicles that are able to do more harm (heavy vehicles) require additional licences
7) Vehicles must be registered and a record of vehicles and their owners is kept by the state
8) Before operating a vehicle, you must have third party insurance to cover any injuries you cause to others (and in many jurisdictions also to cover any damage done to their property).
If guns in the US were regulated just like motor vehicles are, there would be far fewer gun owners and likely far fewer shootings. But if you even hinted at bringing in such a level of regulation, the NRA would have a fit.
