Thank you K for your prompt reply.
Actually I need to analyze the images that I capture with a software package
(Labview) in real time, or as near as possible. I would prefer that the
equipment remains stationary. I need more technical details about the type
of equipment I need, i.e. how to work out how much detail I can get
(smallest feature I can detect), with what type of equipment. For example
say I want to detect the door handle on the vehicle from the side of the
road. Is that possible at all? and if so what equipment would make it
possible?
Thanks again.

A number of methods come to mind, bare with me here as I'm dosed on
medication and prone to make little sense at the best of times..
One method is to clamber aboard a vehicle moving at the same speed in the
same direction then pick whatever lens suits the angle of view you want
(50mm is boring but a 20mm looks nice if you can get low to the ground!)
Another technique involves panning with the vehicle as it passes you, again
choosing an angle of view which best suits your needs..
Finally you could stand 40 feet back with a fisheye and get the vehicle pin
sharp at 1/500th of second but it'd be kinda small in the frame.
For a sensible comparison of focal lengths created by me in a more lucid
moment, see here:

in this page the word 'perspective' means distance. I find the series
helps comprehend expansion and compression of detail relative to angle of
view better than many of those pages which show a whole mass of buildings
progressing from teeny dots to a single framed window
..if you catch my drift
Personally I'd prefer to travel at high speed with my subject, it's kinda
fun and you have plenty of opportunities to take lots of shots
