For me, this is the major selling point to own a car. I may drive a few times a week, and taxis might be much cheaper, but no way I'm going to deal with human taxi drivers if I have a choice.
I always (as soon as I could) owned a car, first on independence, but soon that became on price. A car costs between $350 and $500 per month, plus about 2 gas tanks, let's say $600. That's only 10-15 short taxi rides and two long taxi rides at best.
And now I have a family, there's 5 of us. A car is easily less than half the price of public transport for what I need to do (because you pay per person).
I hate traffic, and I don't really like driving, but since a car is easily 30 minutes faster than public transport to drive in to work, sadly 30 minutes of traffic in the morning is still faster than public transport, no matter how annoying it is. Oh and no waiting in the rain/cold is a nice bonus.
Taxis are not a replacement for having a car for commuting for like 99% of people
This seems weird to me, maybe it's a generational thing. Is it really that bad to share a car with someone? You don't have to talk to them the whole time.
