Seems like the worst case scenario for piston scuffing and harsh bearing loads on the fired-cylinder. Any engineers who can weigh in?

The regen uses the alternator, not the starter. The starter and the battery are bigger to account for the added cycles from start/stop. It doesn't bother me, but my car is a stick so I control when it shuts off. Has to be in neutral with the clutch out.
I have an automatic MB C300 as a rental this weekend, it is an automatic and the stop/start is fairly irritating - too quick to shut off, though it does restart very quickly. Weird car - love the look inside and out but incredibly cramped and the ergonomics are a hot mess.
