I see from your profile page that you have no children and thus cannot or will not understand how a father (presumably driving), mother (w/1 child on her lap), and 3-6 other kids Plus Grandma in the small back seat together sitting on laps and w/the family's dog or cat, PLUS survival supplies enough for all that crowd...clothing, food, medicines, water, first aid, etc....is evidence enough that that family w/laps needs more than a compact car.
You try that scenario just once and get back to me.
