Our City police did exactly that.
The regularly set up a photoradar van, followed a short
distance down the road by a LIDAR gun. They do a booming
business as people speed up thinking they have passed the
'obvious' radar van.
The Cops have also taken to using their LIDAR gun from
parked City utility vehicles (e.g. dump truck), and
again do a booming business nailing people speeding through
a 'construction zone'.

Whatever it takes to make people slow down for safety.
The Cops recently clocked people doing 160km/hr in an 80
zone. That SHOULD be an automatic license suspension, but
it isn't, yet. It IS an automatic court appearance.
