I’d guess a greater percent of car owners in the US are working class. A lot of cities car modal share is like 85% or higher which shows how much car ownership is democratized in the US compared to asia or eu, where ownership might be higher relative income and more able to afford new ev premium prices vs cheap used gas cars.

Another interpretation of the high modal share of cars in the US is that there are no viable alternatives to driving in many US cities. In Europe, public transport and biking are viable forms of transportation, so we're not forced into car ownership to participate in society (although the situation can definitely still be improved further). I believe this to be a more "democraticed" outcome than an inescapable 85% modal share for cars.

We're talking about new cars, which in the US the average price of is $50K. The working class tends to buy used cars, of which 3 times more than new cars are sold each year.
