Thermal expansion of steel is .0000072" per degree F. All you would need is a 100 degree F temp change to blow that tolerance out of the water. And 100 degrees is not that much when it comes to cars. A freezing cold day versus a boiling hot day in the summer is a temperature swing more than 100 degrees. A ICE engine runs at roughly 250 degrees F so that right there would easily expand parts way more than the tolerance he is calling for. On an EV, I don't think anything gets that hot, but the motors still get warm.

Is that per inch or per foot?

But one unch of material doesn't dilate as much as one foot of the same material. I guess that's what they mean when asking "per inch per foot?"
