If so, then tell us the road, time and date, and submit your entry. We'll blank out their plate, but they'll know who they are when they log on. And so will their friends. And their boss. And everyone else will laugh at them too.

OK, the first thing to get clear is that photography in cars can be dangerous. If you are gazing through a lens minding your f-stop (photography term, keep with it) and a truck wanders into your lane, you will probably end up eating Armco. Not good.

So, we recommend that ONLY PASSENGERS take photographs of middle lane morons. You should also be careful NOT TO DISTRACT other road users. Flash photography, especially at night, should be avoided - so turn off the flash if it is automatic. Leaning out of the window giving them the coffee bean shake could also divert their attention from the road.

Technically, in car photography is best with a fast shutter speed to prevent camera wobble and in-car vibrations blurring the shot, which can be difficult if the flash is turned off. So a good, bright day is required. Auto focus cameras may also have problems focussing through glass, so if this is the case, manually set your camera to an 'infinity' focus. It should be fine for taking shots of other vehicles on the road.

Finally, always say 'Smile, you're on Middle Lane Morons'. They may not hear you, but you'll certainly feel better taking the first step towards naming and shaming them.
