Just beware ok for those test top speed...

What we heard... if drive above 200kmh, speed trap cannot detect the speed...
The reality is....... even we drive 300kmh, still police can snap the speed within 3 second..

What we heard... if use hi beam all the way during we cruise with high speed, police kenot snap the speed..
The reality is....... rear vehicle got hi beam?

What we heard... GPS help to detect speed trap location
The reality is....... but when cruise say at 140kmh, once GPS alarm the location already passing by....so what purpose?
