Chapter three, question 2

Chapter three of  Naked Economics, it talks about a family that needs to buy a large car for space as well as safety. I can relate to this because in my family there are three kids and none of us like car rides. We need a car that is big enough for all of us to ride at the same time. When buying a new car this summer, my moms biggest concern was safety. That was the first question she asked for every car we tested. The book talks about putting a tax on large cars because of the amount of pollution but I don't think it would be very effective. I think people would still buy large cars because of the safety factor. Large cars are much safer than say a smart car.
