Electric vehicles can use regenerative braking for the majority of the time in normal driving. Brake pads can last substantially longer on hybrids and electric cars because of this.

With stick shift cars you can use the engine to brake and get the same brake pad savings

  You can but very few people drive stick in the US and, of those, I suspect very few use engine breaking for a significant fraction of their braking. For getting off a highway maybe, but probably not for stop and go in a city.

    In fact engine breaking is illegal in most populated areas

      This is not true. There are specific areas that ban it and have signage alerting drivers to that fact, but it is not common. Plus, it typically only applies to Semis as their engine braking is especially noisy. On a typical gas powered sedan you would be hard pressed to identify that someone is engine braking unless you were right next to it. Being prosecuted for it would be even more exceptional.

      That kind of engine braking (the kind trucks do that's extremely loud) is completely different from "engine braking" with the transmission

  ...at the expense of piston rings and other expensive, hard-to-get-to items. And, an educated guess here, probably increased emissions on the overrun. Besides, who drives stick anymore? I've driven stick since I learned to drive forty years ago, and I even I admit that I can't do better than a computer-controlled DCT, on performance or fuel efficiency. Next car is either electric (we already have a Leaf), or DCT if we must.

Increasing wear on expensive, hard to replace parts (your engine and transmission), so that you can save on relatively inexpensive, easy to replace parts (your brake pads)

      This seems like a bad tradeoff. Increasing wear on expensive, hard to replace parts (your engine and transmission), so that you can save on relatively inexpensive, easy to replace parts (your brake pads) So that's not actually the tradeoff you're making. More to the point you run a much higher risk of acute failure with brakes than with anything else. When that happens on a downgrade you can't stop. If you were actually increasing wear on piston rings (a laughable argument at best) you might end up needing to rebuild the engine after a few decades.

    There are no fuel emissions when you engine brake in a modern fuel injection vehicle, as fuel intake is stopped [1]. But it could be bad for your piston rings and catalytic converter [2], so there's that...

  Or just use the Cruise Control speed toggle on your automatic. At least on mine (BMW) it engages regenerative breaking when you click down the speed.
