According to Sean's email link, if it is a Gatso and flashes at you, it cannot get you. There is one which does get you from the front, a Truvelo, but it uses an infrared flash which you don't see.
The only front facing camera that can catch you is the Truvelo, but this doesn't flash.
Just hope this is legit - too many points already!!!
Cheers for all your help.
Any more info re 5dr 2.0GX's gratefully received.
