Here in Italy the FIAT 500 was the first "family car" and was less than 3 meters long, the FIAT 500 Giardiniera was the station wagon version and it was 3.1 meters long. If you look at an old 500 now, you'd wonder how would a human fit inside.

Today's average SUV is over 4 meters long, with some going over 5 meters. In Japan there are Kei cars used as trucks, people movers, vans etc. The fact that you need a Jeep compass to be able to pick up your kid from school is absurd
