Also remember that this isn't all good.
With shelter in place orders and people self quarantining there are car dealers, especially independent (i,e, smaller, non-major company) deakers who have lost business almost completely and have had to lay off their staff indefinitely...
While this may not be very different than other businesses, these small lots and dealers of multiple makes with smaller sales are not likely to survive very well, and many are family operations that have endured for years, if not generations. Even the large dealer chains tended to grow from the expansion of family-created dealerships and they have been the backbone of the industry.
So gas is cheap. It doesn't matter if the oilmen bringing it to you domestically are gone and your can't find goods to drive to buy and YOU CAN'T FIND A CAR IN THE FIRST PLACE.
No cars, the parts suppliers collapse (and guess who was making a lot of parts for them)?
Too late to bring Studebaker back to make wagons.
