Love or hate them, automobile dealerships aren't going anywhere in the US. The strict dealership laws and the powerful dealer lobby behind them all but guarantee that the established brands won't be able to offer direct-to-consumer sales anytime soon.
Meanwhile, the dealer's job of understanding and explaining how the vehicles work has been getting more and more difficult as the tech inside the cars advances. Then add the fact that more and more alternative fuel vehicles are showing up on the lots in the form of battery electric vehicles (BEVs), plug-in hybrids (PHEVs), full hybrid electric vehicles (FHEV), and hybrid electric vehicles (HEV). You can quickly understand why dealers need more help and training than ever before.
