Question of the day

Why do cops pull over people during rush hour when there are 50 million cars on the road? I mean, seriously, what could people do so wrong when it is literally impossible to speed? I really think these cops that pull over someone every. single. morning. are idiots. They just cause more slowing, which causes more backup, more pissed off people, and therefore more accidents. The only reason a cop should pull anyone over during rush hour is if there is an actual accident.
