So my drive to Montreal from Toronto took 4.5 hours with a total of 3 stops along the way. Our average cruise speed was around 150 - 160 km/h (95 -100 mph).
Got a few X falses, but had a real K band threat just on the 401 East beside the "Brockville" sign. I got plenty of warning, before and after the threat.
The OPP had a car pulled over.
Did not see any Ka band and I am not sure what frequency the K band radar was.
