When drive with other cars in the front and behind me, I keep noticing that other drivers don't follow me at normal distance. They start out behind me at normal distance. Then they keep their distance farther back. I am thinking it has something to do with the regenerative braking. Either... 1. Regen braking is not consistently turning on the brake lights and the drivers are being cautious. 2. Regen braking is turning on the brake lights too frequently that the drivers stay farther back. Which is it? Or is it something else?
