One mechanic that doesn't get enough hate is the 'follow this guy - but don't get too close!' mission, usually complete with a 'spook-o-meter'. Apparently, calmly pulling up behind the target car at a red light and waiting to continue puts the freaks up any potential crims far more than a car performing several handbrake turns in the middle of the street around 100 yards back, banging into several cars and knocking over fire hydrants in the process.
