So would that mean that California has actually gotten fitter in that period of time, since it appears to be the only state with no visible change? (Edit: Michigan as well)

You can plainly see that there’s plenty of other material sticking out much further than any 1cm extension. If you were in a crash that ate through all that material first, I’m sure the engine casing would be the least of your worries.

Extend the length of the drain plug by 1cm? Something something, profit.
