Enforcer

Enforcer, known as Limit Watcher (リミットウォッチャー) in Japan, is an enemy from Mega Man ZX Advent. Enforcer is a policing Mechaniloid that enforces speed limits in the Highway. It chases down offenders, whether they are in a car or not, and warns them about speeding. They usually fly slowly in place, but if the player dashes past them, they will chase you in pursuit.
