I really dont know the obsession with this bigger cars thing. The freedom to go anywhere and carry a lot of things... moar moar MOAR!
I had a car, a Ford Ka. It wasn't thw best but it was perfect for me. It was small, ran a lot of Km with each liter of gas, was fast enough and ample enough for what I needed.
I recall refueling it once per week and sometimes even 10 days between refueling. And my work was 15km from home. That's 30km round trip per day. All this just refilling before it got half tank to preserve the injectors and don't put strain on the gas filter, so in practice it have worked with even more scarse refilling.
I never needed anything bigger and in fact could have done it with a smaller car. Going to the beach? Well I could have done it very well in it. Camping? Who really does it here? Nobody, that's who.
It's like the people getting huge pickup trucks with double wheeled rear axles, 5 seats and several tonnes of cargo capacity.... to drive to the office and leave children in the school. It migth be afordavle here but Im pretty sure anyother country in the world is far more cheaper just to hire a van/truck for the very few times in your life that you are going to actually use that cargo capacity or rent something for that outroad trip that pay years of large gas tanks and expensier tires and spare parts in general.
Obviously there's people like contractors, deliveries or the like that do need this constantly, that's fine, but the large majority of people... bah...
Sorry for the rant
