Not just regenerate power on braking, but regenerative braking also means fewer consumables in the form of brake pads. Which, interestingly, the dust from pads is third after tires which is second to the ICE engine. The other thing we've still haven't had enough time to fully discover is how much individual cells wear out and the big picture of the economics of swapping out only the individual cell that's bad. There's already been some practical work doing that, I'm just not aware of any longitudinal studies about it.
