1) I think whenever the vehicle brakes the brake lights are lit, regardless of what's actuating them.
2) I hadn't noticed that, but I was surprised how quickly the car accelerated down hills during eco coasting. I end up needing to use the brakes a lot more often.
3) I wouldn't trust it to do that, but if you keep it on you may be able to feel out where it would have steered. It will slow the car slightly in turns sometimes, not sure how the logic works.
