I work in Supply Chain, and you're right about disruptions. My company employed more than 100k truckers in 2018, now we are down to 35k and we pay more than anyone else in the industry by far because our CEO is a former trucker.
We have weekly meetings where we basically have to decide what gets shipped where and triage what is most important. There are mass amounts of food just rotting in shipping containers all over the country. There's medicine and soft goods just gathering dust in the Port of Los Angeles and South Florida.
We were prioritizing gas heavily, but food is quickly starting to take over in importance due to the spoilage, which means gas prices are about to go up A LOT. Like 1-2 bucks a gallon in the next 45 days or so.
Our company doesn't do it, but I know other companies have government advisers who help with the triage stuff, we stay independent and work with our customers - the stores and shops - and let them decide what is most important and take that into account.
Many are worried about being away from home when the SHTF.
But most are hating the big companies that have bought the trucks and make them lease them.
