Its called rear curtain sync.
Set a slow shutter speed to capture the light trails, tripod mount the camera, click shutter, get someone to drive car into frame, park it in frame at a pre-determined point, then just before the shutter closes, the camera will set off a burst of flash, hence car in lovely detail.
I'm sure Ukaskew will be along soon with an example of his fine art

I doubt mine has this rear curtain sync thingy, but I shall have a look.
Is it only going to be the sort of thing you're going to get on high end cameras?
Cheers for your help guys.
