Doesn't every gas motor start spew out some uncombusted fuel ?

  Maybe? I think direct injection motors are actually pretty good at reducing that. Catalytic converters help too. But yeah, there’s more waste than an electric motor. The reassuring thing to me is that in just over 100 years we made the ICE so efficient. It’s a fundamentally wasteful design and we have taken it very, very far. With another 100 years of battery and electric motor development we will have equally impressive capabilities with the added trick of energy source agnosticism.

    When the engine is warmed up starting it doesn't AFAIU cause any big pulse of pollution. Also vehicles equipped with these stop-start systems AFAIK have more powerful starters so they can start faster.

  There is a little bit of waste associated with engine start, but it is worth it if you are idling for more than +- 10 seconds.
