I know my comment is off the radar. Since some of you are talking about how boots of the cars are getting smaller and I agree, but we should also look into design of the luggage. Personally, I never liked design of 4 wheels poking out bags and avoid them purchase whenever possible as it takes up unnecessary spaces and not stable as they roll up and down when travelling on trains or buses when you are not holding on to them, but most of bags are designed this way these days unfortunately for fashionable reason rather than practical. So, instead of just talking about how small the boot spaces of modern cars, we should take a look at the design of travelling bags. I am saying this as I travel often and experienced with bags taking up the spaces with wheel poking even on station wagons.
