5-0 Lookback

Verb: The act of driving past a speed trap, then looking in your rear view mirror to see if the police are chasing you.

Even when I am driving under the speed limit, I always do a 5-0 lookback until my heart rate is back under a 100 bpm.

Even with a built ls3, ported heads, blower, full exhaust, tune, and 75 shot, Bills ZL1 couldn't fend off non liberal's 2013 5.0 Coyote Mustang.
