> Police in the US are rightly very afraid when pulling over someone for something petty like speeding because that person could be upset and have a gun. Where I'm from cops are not afraid because nobody has guns.

this sort of begs the question of why direct, in-person confrontation is even necessary for petty offenses. there's always a risk that such an interaction could go south, whether or not guns are involved. to write a ticket, all the cop has to do is record the measured speed and identify the vehicle and driver. with the tools available in 2020, they should be able to do this without stopping the person to ask for their license and registration. save the confrontations and arrests for when the person clearly poses an imminent threat to those around them.
