Can't say for sure, but an old mate of mine [now retired*] formerly employed by a State road authority told me that there would be gantries with banks of cameras in the near future feeding info to number plate recognition software which would compute average speeds for sectional distances between intermediate cameras on such [then proposed] long lengths. Theoretically that would mean that multiple tickets could be issued to the same vehicle on a single trip i guess.
*Retired from that employ, not as my mate of course. Nobody would ever wish to terminate my acquaintance 'cos i'm so nice to know.

$1 a klick is mate's rates and much better than Uber, but i can see you're broke or you'd upgrade from a pre-Jurassic 765 obviously. Not too bored at present however will load latest Cyclops and check in simulation eventually but may or may not bother to tell you the result. [Probably will do it and report with some screenshots tomorrow or next day champ, stand by].
