GM had side-saddle gas tanks that would behave quite similar to the Pinto in a collision. There were some very stupid decisions and design choices made in that era, neither company was actively trying to burn people alive.
You want to talk about ethics and bad corporate decisions?
- Tepco was aware of the deficiency in, and implored to upgrade, the seawall and relocate the emergency generators to behind the facility at Fukushima. They didn't.
- The company that constructed the bridges in Montreal (mafia was involved) used substandard concrete and construction methods to redirect money to pay off bribes and skim profits. This resulted in chunks of concrete falling on cars, killing people as well as complete bridge collapse, causing multiple fatalities.
- The Sukuki sidekick would roll if you looked at it wrong. GM knew that and still used it for the Tracker.
- The Neon and Cavalier had some of the worst safety ratings in history and the incidence of fatalities in collisions made them stand out by a massive margin. That didn't stop GM or Chrysler from producing them.
I'm sure we can think of plenty of other examples if we take pause.
