He covered this pretty well. Diesel engines have also been experiencing similar amounts of increased complexity (and decreased reliability) as a result of emissions standards.
That really got me thinking - people say CAFE and stuff is good. But there is an optimal slope of regulation tightening that is ideal. Too fast and you end up with out of warranty reliability compromises. The thing is, too slow is seems to actually increase reliability. Look at the 90s. CAFE was the same from 1990 to 2010 for cars and light trucks picked up steam in 2005. The 1990s produced some of the most reliable cars that we have seen. And for trucks, like for GM, they started introducing stuff like displacement on demand to combat the rising truck CAFE standards. And we all know that DoD is a pain in the ass. This is just fuel economy. Emissions also lines up fairly well as Phase I went from 94-99. Things tightened up again from 99-03 and again from 04-09. You can literally see a trend there. The LS1, for example, was a perfect result of fuel economy, emissions and power requirements, because they came through the technology. But that isn't always the case, and the consumer of the used car out of warranty foots the bill when things don't align so well.
EVs basically zero emissions at point of use but then we pretend that coal doesn't account for 39% of the electricity production in the country.
