Families don't need 2.5 tonne SUVs or 4 seat trucks. They don't need Volvo XC90s or Escalades. Sorry. They just don't.
And the reason everyone is going on about "car size inflation" and how it was fine in smaller cars 20 years ago is the same reason - you didn't have to use child seats. Now because of safety you literally can't have a family larger than 2 children with a smaller car.
