Radar detectors don't help in all situations. My V1 saved my *** 3 times this weekend coming down from Tahoe in the TT. In every case, I was going about 85 in the 2-lanes-per-side of HWY 50 in the mountains. The detector went brap and I nailed the brakes to 55 - each time about 1/4 of a second later the CHP came around the bend in the other direction. Gave me a look but nothing he could do. By the time he had visual on me someone else was going by me!
