Can camera vans get you when facing towards you?

How easy is it to get the motorcyclist - small target long distance or is it some sort of auto focus tracking. You are in the sights but as you are coming around the corner very easily you quickly are out of the track - unlike a car that is wider how long does it need with an oncoming to register a speed. I am confused because If you are followed by a car they record your speed over 1/4 mile ? for evidence or have I got that  wrong   

Well the vans (or police stood with a hand gun) are usually parked to one end of a straight road so once you are on that stretch coming towards them, your position wont deviate much to the left or right - unless you weave side to side between lanes (if there's more than 1 which "could" be a tactic)

Granted, on a bike you are 'tiny' compared to the mass plus width of a car - so it would require much greater targeting skill to track you.

.......I don't believe these speed guns have "helmet recognition + tracking" technology...... yet!

The long straight road position is fine but that is always either after a bend or brow of a hill. So as I come around the bend I spot the van way up ahead up the straight, throw the anchor out and they have not had enough time to lock on to my small target so my the time they have a fix on me I am doing the limit.
