I don't get that. Surely people still need to travel, and are less likely to take public transport, wouldn't that drive up demand rather than drive down?
OK people might not be commuting 5 times a week, and perhaps doing fewer miles overall, but you'd still need a car.
If you live in a walkable city, then your requirement for a car hasn't changed if you are no longer walking/subwaying to the office
Those with good credit and a reliable if not older working car probably aren't buying cars much right now, but these people definitely are.
They might not be allowed to...
Data point: I have two vehicles parked outside the house right now, I have purchased exactly one tank of fuel for each of them since the start of March.
My understanding with americans is that having a car is more essential than having a house
