The automation that new manufacturing plants have is amazing. Started in the eighties. Where manufacturers found out....DUH.... when the workers are comfortable making product....the product quality goes way up. Gone are the sweat shop car plants of old. Just go on youtube and see how those autoworkers worked in sweat shop heck. Now even the factories HVAC is filtered to make the best product possible. Yes there are some problems. Alot of it federal Government mandates. it has been that way since the sixties. But in the past few years automakers had just had to deal with CAFE...mostly. Thatis why you see big vehicles with turbo 4's in them. That can be a problem...yet. Time will tell.
