That may have been true in the 1970s, but light truck and passenger vehicle emission regulations have been identical for a long time. Looser fuel economy standards for light trucks certainly causes manufacturers to push them harder though.

CAFE standards were responsible for much if not most of the increase in SUV driving we saw from the mid 90s onward.
