More Than Just Bikes has a great video on how US automakers pushed the sale of gigantic trucks onto American consumers and how it's caused a huge increase in vehicle related deaths.

Automakers were incentivized to sell big inefficient trucks and SUVs to the average person and began to heavily market them as manly/cool/safe. What was once a niche vehicle is now 80% of US auto sales.
