My observation in that all of these things (plus delivery services, Amazon, etc.) can make a difference at the margins. If someone doesn't have a daily commute (or has a reasonable transit or bicycle/walk option) and otherwise isn't transporting themselves, other family members, home improvement stuff, etc. on a daily or near-daily basis, collectively they may let a household do without a car (or at least a second car).

A couple I know in SF don't have a car but they seem to make a lot of use of cars in some form or other pretty regularly.
