Coasting Versus Braking

The first question is if I get any more regenerative power when I brake than when I coast? For that matter is there any regenerative power created at all after the brakes are applied?

The second question is if anyone puts any thought into when they apply brakes? Specifically when putting foot to pedal, thus activating the brake light and hopefully getting the attention of the guy riding your tail? Does anyone flash their brakelights?

I ask this because in the afternoons I climb a causeway bridge in the late afternoon and the sun is low enough on the horizon that people are semi blinded. I just trying to be most efficient yet as safe as possible. It is a real concern when I'm just past the crest of the bridge and suddenly the traffic is stopped.

FWIW, I have always coasted to a stop as much as possible and I get high marks on my report card for my stopping. I never could figure out why people are in such a hurry to get to a red light (often the same people who very slowly accelerate after the light turns green).
