Whether the brake lights come on or not is part of regulation that takes into account by how much you car decelerates, with the fact that it can stop you in traffic (with auto) and follow pretty accurately I'd imagine they would.

It can certainly give quite a good bit of deceleration. It slammed on the brakes pretty hard for me the other day when some Einstein pulled out at about 55 into the middle lane while I was passing at 70. It would certainly have put on the brake lights.
