I have a friend who owns a Tesla Model S who says the regen is not as efficient in stop and go traffic as lighter vehicles. The Prius and Leaf are thousands of pounds lighter. (He still loves his car.)
He says the Tesla seems more efficient on county highways than side roads because the losses from accelerating the vehicle's over 4500 pound weight exceed losses from air resistance at those speeds.
