You don't need to give up the car - you just need to reduce car trips.
The easiest way to do that is reduce commuting trips, as those are very common, but you can reduce trips in other ways, such as allowing more gas stations/convenience stores. If it's a five minute drive to the grocery store but a two minute walk to a 7-11, some of those trips to the grocery store will be replaced with walks to the 7-11.
