Anyone with a driver's license and enough money can walk into a car dealership and be "operating the dangerous instrument" an hour later. In this case would the car dealership be liable for a crash? Should they be vetting who they sell cars to? Or what about the state that issued the driver's license? After all, it's their actual job to vet drivers. By your logic the DMV should be liable for every accident caused by a driver with a valid license.
