Keep thinking about this VMT data from new NHTS. Very counter-intuitive — fewer cars should mean more VMT (everyone using one/ two cars to do it all). But in multiple vehicle houses, one member is commuting really long distances and everyone else also has a car to just do basic things in the sprawl.
The 3/4/5 vehicle is probably to go get bread from Walmart or something. This vehicle is probably very old with terrible emissions standards and will kept in the fleet for a long time “just in case”.
I would think the N on HH with more than 4 vehicles has to be pretty low.
It may also be that to keep that many vehicles around you prob live in a VERY car-dependent area that is exurban or rural area - at least that’s what I imagine. You can’t give up a car if there aren’t viable alt modes
