The key word there is disappeared which means engineering effort was put into vehicle design to make it a non issue. more robust/new starter design, more expensive battery tech required, simulations to validate no carbon buildup and real world testing, software calibration to make sure if engine is too cold or turbo too hot doesn't auto stop. All driving up costs to consumer thus consumers would liek to have something for that added cost. For many rural drivers a typical commute may be 15 miles with 2-3 stoplights and 1-2 lights. this effectively negates the fuel benefitsand often is annoying when coming to a stop at a stopsign to have car turn off momentarily for no benefit and possibly detriment to fuel economy if the ratio of stop sign initiated auto stops is higher than stop and sit at a stop light. I do appreciate personally the moments of quiet when not moving but is it worth it the added cost to my vehicle ¯\_(ツ)_/¯
>>often is annoying when coming to a stop at a stopsign to have car turn off momentarily for no benefit
The benefit is that it's nice an quiet. I don't care about the fuel saving.
>>it worth it the added cost to my vehicle
I'm not sure what that cost is, even if there is one. My XC60 got rid of the starter motor and just uses then ISG which it would have to have anyway being a plug in hybrid. The engine obviously has to start and stop at any moment to allow EV running too, so that engineering had to be done anyway.
But I had one of the early S/S systems in a 2013 Nissan Qashqai and I never had any issues with it in my 7 years of ownership, not entirely sure if it added anything to the price of the vehicle as the previous model year with the same engine but no S/S cost exactly the same.
