If your number plates are being flashed to you from another car, resist the urge to stop - they might be hijackers.
According to an e-mail doing the rounds, hijackers are removing motorists' number plates in an attempt to get them out of their cars.
They "stalk" motorists to a parking lot or mall, wait for them to park and leave their car before removing the plates, the e-mail says.
The hijackers wait for the victim to return, follow them on to the road and then overtake them while displaying the number plate at their window.
