I just got back from my 4000km+ road trip, and I have found out several things to share with everyone. (might not be new information here)
During the entire trip I have taken some major route & city in Canada. Such as, Highway 1, Highway 5, Calgary, and Edmonton.
I found out cops tend to be using more K band in urban area, maybe because of radar detector tend to be giving a lot of fause alarm in the city. On the highway, highway patrol car uses onboard Ka band radar most of the time. During the entire trip I had no chance to hit any lidar speedtrap, so the I have no idea on the effect of veil and laser shield. But one thing Veil guy should really work on is to lighten the color of veil. I had really difficult time when driving in the dark, cuz the veil has made my headlight became candle light.
