When city driving, I never hit the boost, engine temps are struggling to get up, luckily I don't need to drive in city that often, even rare is that I would meet traffic lights.
I turn off engine at traffic lights, but mostly when I know stop is tad longer, cool off is happening all the time at city driving, that is if you are driving sensible, as one is idling most of the time when hypermiling at city, so there is no difference for me when turning it off normally or at traffic lights.
It is not really fuel saving, but noise saving, why to keep making lot of noise when one can sit in silence?
Don't know about modern things, but I'm not too fond of them either, I can make old one to go as little or even less fuel because less of weight
