We have more independent truckers. Truckers that get paid by the haul. With backlogs at ports they have to sit for a long time, time which drastically cuts into their over-all trip times: COSTLY!
The pandemic applied the brakes to spending, consumer and corporate. Factories had to scale back. It's not easy to ramp everything back up, and businesses really should be cautious about doing so as the longer-term trend will be lower demand. That said, however, I'd think that replacement parts production will come back up fairly well as new equipment demand will be lower as folks look to stretch out existing equipment.
Toyota, following Fukushima, learned that JIT (Just In Time) had its downsides. They made exceptions to their stocking regime by bumping up inventory for critical parts. I have no idea how they fared with this pandemic. It would be interesting to see the numbers (compared to other manufacturers).
US "economy" has been totally financialized. This shift was essentially started in the early 70s, just after US oil exports peaked and the USD was taken off the gold standard. The big "marketing" push of the finance "economy" began in the early 80s and mostly completed in the late 90s (elimination of Glass-Steagall). The 2008 banking crash propped up a failing system and that system has been on life-support since: even before the crash the Feds were pumping in money- they haven't stopped.
US can never return to its manufacturing heyday. Well, not unless US citizens are able to work for as low of wages as folks in other countries. But even then there's the issue of foreign markets in which to sell in to: would have to increase the purchasing power of a lot of poorer countries' peoples, which would most likely require a substantially weakened USD (another big hit to US workers).
Demographics (CIA has great data that helps in seeing trends) and resource depletion is setting in. Legislative changes, either increasing regulations OR decreasing them, won't change the fundamental path: only difference will be in timing.
So, to answer rScotty's query: there will be a significant lull in the short-term due to the disturbance from the pandemic; in the longer-term we can expect things to ease up a bit but then flatten and likely slowly drift downward (as long as the US doesn't start a shooting war; if this happens then the bottom drops out and authoritarianism takes a hold of our throats [be it from a Blue or a Red glove- party politics have nothing to do with The Game, they're but a distraction and a divisive mechanism to keep the masses from seeing that the empire has no clothes]). "Parts" supply, as noted above, is likely going to rebound as it's one market that is going to have more demand supporting it.
And remember: "cost" is not the same as "affordability." (I care about "affordability".)
NOTE: I place "economics" in quotes because we are in no way economizing our world (it's been a case of continual ramping up of exploitation and extraction).
