I got rid of my car in 2019, though was evaluating if I need it for about 2 years before it. The main reason why I got rid of it was because it demanded too much attention to stay clean (I like clean cars, don’t care about their brand or characteristics) and money to stay legally roadworthy, while I was making under 2k a year. I understood that it would be cheaper to use a taxi instead around my town if I needed to give a ride to my family
However, I had Honda Forza 300 scooter and travelled around the UK for business - I am a business consultant. It is doable, though once I got caught in Liverpool by Beast of the East and stayed in hotel for an extra day
Now, however, I am thinking to get something like Tesla and a compact electric scooter that can do 50 mph (large wheels though because it is not safe)
I even went hunting on my scooter and brought roe deer
So, without a car is doable, but without a motor vehicle… if you are in a large city
