Also, there is no way to actually measure this tight of a tolerance on large parts such as a car, since the standard methods for this tight of a tolerance measurement is… using a caliper, as using automated optical inspection for every dimension isn’t really feasible.

We definitely have lasers that can measure this tolereance.

Additional fun fact. There has been a lot of research and activity dedicated to potentially switch coal power plants to nuclear. Currently, they cannot do it, because the coal plants and all the equipment associated produces far more radiation than regulations allow a nuclear plant to emit.

Therefore, unless they could find a practical way to decontaminate the radiation away from existing coal equipment, or regulations change for transformed plants, they can’t do it.
