Joining car clubs is a good way to get around in cities. There are many car clubs in the US. You can use a car when you want to, and it’s cheaper than having a personal car.
You only pay for the car when you drive it. You don’t always use the car because sometimes you can take a bus, or walk or ride a bike. This is healthier for the city, as there will be fewer cars on the road. It is also healthier for you.
