The headline on the page is "The Real Reason Why Trucks Are Getting Bigger" - and it is not supported by the item. The assertion is that Obama-era fuel restrictions on cars and small trucks incentivized manufacturers to make bigger trucks which conformed to a less onerous standard.
At the same time, though, we can all agree that there is at least some consumer preference for large trucks. The question is how do these compare? Is the state of play now 95% due to consumer preference and 5% to manufacturers trying to push larger trucks. Or is it the other way round, or some other mix? Todd offers no evidence either way.
