!laser for slows speeds

[Adorable]

To prevent abuse, a system could be implemented that will only start to take laser measurements that are <30 kph only if the car has been driving less than 30kph for atleast (say) 10 seconds.

Like when changing from a speed limit (120) to a lower one (100). There's a little delay before you can start taking laser measurements. Same could apply for the suggestion at post 1#

€: Anyways, It's not really that important. Witnessing someone doing <30kph for quite some time is enough to fine him.
