I don't drive, and instead spend what sometimes seems like a fortune on Uber. But in the UK the average monthly spend on a car is ~500GBP when include the amortized cost of the car itself.
Even when my son was swimming competitively and we had to Uber him around to 6 training sessions a week plus often competitions many miles away, I only briefly averaged 400GBP/month in total transport costs (though with the caveat that I work from home; had I commuted full time it'd have added ~200/month to get in to the centre of London, but then again I'd likely have spent that even if I had a car because commuting in to the centre with a car is a nightmare)
And I got to sit and relax and read or talk to my son or listen to music and not have to pay attention to the road.
I get that some enjoy the actual act of driving and/or driving a comfy, fancy car, but for many, it's a really expensive enjoyment and I suspect a lot of people have not considered just how much they could "paper over" edge cases and issues with public transport (yes, I know this is not a viable options for huge parts of the US) or choices like yours with Uber or rentals.
