I drove past it today and got very little warning with the V1 - approximately 100m from the front and 20m from the rear. They were messing around with it again though, one of the units had its cover off and they were tinkering with the optics.
I decided not to bother going past more than once from each side as they were messing around with the unit and the location isn't very good for testing purposes being on the crest of a hill. I would've liked to see better performance from the V1 but it looks like most tests will be inconclusive until the police start using the Poliscans properly.
Thanks for the heads up Cosmo
