Whereas, in Europe, the official emissions figures are arrived at using a test which gives an advantage to stop-start, so you find it being fitted to more and more new cars.

That'd be a great way to do more in the US easily. Doesn't (to my knowledge) require massive investments in new/untested technology, and can be adapted to current platforms being built. As much time as people in the US spend at stoplights, it'd save a lot. Someone on here once posted research saying 20% of all fuel is wasted at red lights.
