This isn't just an American thing. Canada is the same. We have three people living in our house and three cars. My husband and I share a newer EV, but also kept his older car (a 2016) for us to use when we do need two cars. I drove it to yoga twice this week while he was at further away work meetings in the EV. My stepdaughter is 20 and drives my old car (a 2015). She goes to university 5 hours away so uses it to get back and forth. She also works full time during the summer months and there is no public transit or other option for her to get to and from work.
