Vehicles also act as large portable storage, which is very convenient when you have kids. e.g. stroller, diaper bag, change of clothes, sports equipment, emergency supplies. It would be annoying to always have to keep things on your person. With a personal vehicle, you also don't have to worry about something falling out of a bag and being lost forever after the vehicle drives away, or accidentally leaving a piece of equipment in it; just go check the parking lot. Or what if you want to make a trip to multiple stores and want to keep bags from the first in the car while you're in the second?

EVs also have the potential to act as large backup batteries for your home.

You can also choose how to amortize your costs. My mom's been driving the same car for 22 years now.
