Actually, this would have come in *real* handy in getting me out of the situation that ended up in 3rd degree felony evasion!!! (I tried to ditch a cop once in my '74 Stingray when I was racing another car and saw the other car take off down a side road after seeing a cop pull around - it was fairly innocent...I figured that if he didn't catch us both, neither of us could get 'competition' or 'exhibition' tickets, so I darted off down a side-road too...BAD DECISION.) - I plea bargained down to class A misdemeanor 'failure to yield to a police officer's signal', and only spent 15 days in the can for it.
Boy, if I only had a smoke screen on my 'Vette 15 years ago! (then I'd probably still be doing all kinds of detrimental self-destructive activities - this one experience was certainly a life-changer!)
