Only you can decide about your need for driving a car.
I could not do without one. My route to work is 20 minutes by car and an hour by public transport. That is over 1 hour for both ways I save per day. Over 200 hours per year that I would spend in full public transport alone for work.
Doing 1 shopping trip per week with the car saves time too.
Plus every other ride and event I like to be part of. Friends and family are 10 to 30 minutes by car away for spontanous visits and events - not a day trip with combined 2 hours of public transport that makes me think twice.
I only 2 times used a car when traveling, that was on canary islands. You literally need a car there to drive up the mountains and see every hidden place that you would spend day trips by bus instead and then still "only" see the few tourist attractions and not able to hold and go anywhere.
So after all, I can only say that YOU must decide. Actually GETTING the license is just a matter of learning (theory) and practice (the basic needed hours are more than enough).
The eye test can be done in almost every glasses store for few money.
The first aid takes some more time but you cant possibly fail it, so its just sitting through. (and its skills worth having, you could possibly save a life, even when not car related shit happens).
The money is a thing, but noone but you can judge about your financial situation in relation to the profit of having a licence.
