I have had my ProPark for about 2 weeks now and have not had a way to test it. The Osprey Laser speed/range scope does not set it off as it is not a speed gun. I could only rely on the self test and parking distance beeping to know if it worked.
Well today I was driving through toll gates that had a speed notice sign. I was doing about 80km/h with a car about 100m in front doing the same speed. I saw the warning sign to slow down to 40km/h for the car in front and then the Propark started beeping (quitely) and the sign displayed nothing even though I was doing 80km/h.
I did not know it was a LIDAR based sign, so I was not expecting the propark to jam.
I just thought I would let you all know it does work.
I am just waiting now for the new Pizeo speaker as it is hard to hear.
