A jerk needs to be corrected when his actions pose a risk to others with what ever force is required. For example the wheelie poping jerk at motorcycle rallies, the guy who speeds excessively through you residentual district (children play outside here). That guy with the dog that gets out and bites people, and yes the person who nearly runs you over in traffic (not on accident) but with blatant diregaurd for you and others around you.
