Why is that better than the police officer who was going to pull them over just using a speed gun?
shrugs
Less likely to be noticed by drivers or alerts like on Waze. Probably a bit more costly though if they're using helicopters or planes instead of drones.
It seems like if the purpose was stealth then they wouldn’t have a sign announcing it.
Deterrence. You never know when they might be monitoring you above, so watch your speed.
