Dude hollywood youre the man!
But seriously folks, the best radar jammer, radar detector, is your MIND!
Using intelligence you can avoid any ticket.
If you see a bunch of cars stopping in front of you there is probably a cop.
Dont speed in any area that you cant perfectly see a clear route ahead of you.
Watch out around exits, over passes, foliage, and curves.
If you cant see perfectly ahead that there are no cops then dont speed until you get through that area.
The list goes on and anytime Ive been actively paying attention and using this deductive reasoning Ive been able to speed my ass off and not have any trouble. All the tickets Ive gotten involved me not really paying attention.
