If you must attempt to beat speed cams, Top Gear tested it and it's only possible if you go beyond 140 MILES PER HOUR. hehe
hmmm... that's a bit fast already.. around 225 km/h. if you intend to find a way around those speed cams. speeding up is very unadvisable.

check out the other thread and just remember where those speed traps are. and if ever, slow down for your sake when you hit those speed traps.
