No car. Is this an option?

18 months ago my wife had an accident with my car. She wasn't hurt but the car was destroyed. I decided to start the experiment of living without a car. Frankly up to now it proved to be cool. No stress for parking, for refuelling, for being stuck into traffic jams.

Ok now I will most probably soon have to buy one again because child n°2 is arriving in our lives. I'm thinking about buying a Toyota Aygo because it only burns 4.1L/100km in mixed mode (diesel version).

But think about it. Do you really need a car?
