My assertion wasn't I assumed that people aren't making a conscious choice, but rather that they aren't pouring over international carbon emissions data as part of that decision making process.

As far as what families feel they "need", I think it represents a larger societal issue around how we manage vehicle use and ownership. Most pickup trucks I see on the road aren't hauling cargo. And most 7 or 8 passenger SUVs have 1 or 2 people in them.

> Also, heavier vehicles are safer for the passengers.

Yes, for the passengers in that particular vehicle. More dangerous for others on the road who can't afford or are unwilling to purchase a similarly sized vehicle.
