I used to live on the Peninsula and know what you mean. It's worth mentioning though that you don't need a shop, or multiple, in every building. It would be enough for there to be a smattering of convenience stores and basic common services like barbers and salons. Moreover, they are not meant to be driveable so long as the surrounding density is sufficient. Polk Street in SF is very inconvenient to drive to but the shops there seem to do quite well.
