Should I give up my car

On a main bus route and shops nearby , sounds good to me ! In your situation I would give up my car and taxi if necessary. Think of the money you would save !

Could you work out the weekly/monthly cost and whether that would be enough for the occasional taxi eg to hospital or anywhere not on bus route or at night. Once you give up your car you are unlikely to get another.

You could try not using the car for say, three months, and then decide?

I know two people who have given up their cars and are managing very well. Both say they don't want to go back to driving and are saving money on all the car expenses.

If the cost is prohibitive and as you are on a bus route and can walk to shops then it sounds as though giving up your car may be the best course of action for you.
