My dad worked nights and Mom was a SAHM who also did some freelance stuff from home. They basically had a first come/first served system, and honestly didn't have many conflicts so the second car (usually the one they've had longer) was rarely used. That was perfect when I started driving in high school, because I could usually use that car (even if it was a few years older than I was)

My brother talked them into buying a used Mitsubishi Eclipse back when it was still kinda cool (an '03 model purchased in 2007?). Mom ended up really liking that car and it's not really practical for the handyman stuff my dad does in his retirement, so now they have assigned cars.

My wife and I have only vaguely assigned vehicles. There's whatever she wants to drive and what I normally drive to work.

She definitely has her car and I have mine. Mine’s over a decade old with over 100k miles, and hers is a year old. I think her car is really neat, but there’s a lot I don’t like about it. Too much tech, too many weird quirks in the systems, and it’s a little compact for my height. I’m glad she likes her car, but we definitely have assigned cars.

Would make the most sense really if you have a narrow driveway where one car is always blocked in, save on the valet parking moving games tbh

One of our cars is a manual, and I'm the only one who can drive stick.

The kids are our deciding factor.

If one of us going somewhere with the little 'uns, then the "family car" with the nicer booster seats gets taken by whoever it is that has them. Whoever is getting the peace and quiet, drives the little runabout.

I usually take the little car, and it surprises me sometimes when I jump into the family car and I've got another 50bhp under my right foot.

We share a single car between family members. And we do not live in the same household or even the same cities / towns.

sharing things with your spouse????

ok one or both partners hate cars. Neither can survive without a car if the other one doesn't have a car. That is a colossal failure, but we'll move on.
