Car, Necessity ?

Everyone around me is telling me it is necessary to have a car because having a kid means more places to go and more things to bring around. But we only go out once a week to grandparents' place and send the kid to nearby enrichment classes. Doesn't need to drive to work, and the kid pre school is just very near our place. Feeling pressured to get a car when I feel it's gonna be underused. At what age the kids require more from getting around by car?
