Culture is just "what people do". It's interesting that train drivers have to be coached through it feeling uncomfortable but necessary for safe operation. If there's a "national character" element to it, I'd say it's the acceptance of the uncomfortable but necessary.

This is what some engineering shops have as standard practice in Japan, which is a distinction with a difference.
