Other harms may not be as obvious but are just as real. There is the danger to personal relationships and emotional health from all those hours spent in the car rather than among family and friends. There is the damage to our environment from burning fuel to deliver residents to distant suburban homes — and the huge cost to our natural systems of building the infrastructure to house them there. Not least, there is the risk to kids' psychosocial development from growing up bored, disengaged and perhaps unconcerned with people who are not like themselves.
