I am fairly open to the argument that price gouging for necessities in times of sudden life threatening crunch is not ok, but car market is operating like a normal market.

Very few people need new car now. Or need to change their car now. It is a flexible market. In the current market supply shortage means that you will have to squeeze 50000 more miles out of your current car in the next two years. It's not insulin or baby formula.
