Class isn't purely economic. It is the perception of 'inner city elites' being out of touch with the rest of the country.

In the recent Australian election, the (losing) Labour Party had a policy to target 50% of vehicles being electric by 2030.

The Liberal party jumped on this and ran a scare campaign that Labour was trying to take away the vehicles that Australians love for work and recreation, utes and 4WD/SUVs. It worked, not because any inherent inferiority of electric vehicles but, because people don't want to be told what is best for them by people that don't understand their needs.
