I don’t think we’ll ever get rid of cars entirely but better city planning and better laws (depending on country) would help the reduction of cars in towns and cities. Make it more inviting for people to use alternative transport.

Most of my food shopping I do on my ebike. Little and often, but I happen to be in a town with nearby shops and quite good cycle route options. If we do use our car we usually do shopping at the end of a longer trip while returning home.
