SUVs started becoming popular in the 1990s but there is significant lag between becoming popular among new car buyers and becoming a significant fraction of cars on the road.
For example SUVs and light trucks rose to 30% of new sales in 1990 but it wasn't until 2003 that they were 30% of vehicles on the road.
