>>508016128 (OP)This is literally because Obama made the emission standards related to the size of the vehicles.
SUVs and Trucks actually have reasonable emission standards for combustion engine vehicles. Hence why they are still being made.
Lots of sedan models got discontinued in 2012.
The majority smaller vehicles on the market that are either older cars made before 2012, economy sedans, hybrids, or fully electric.
There was no widespread consumer demand for these big ass fucking vehicles came on the market, it is just what was legally allowed to be made.
