Does common-sense courtesy differ between cultures?

Yes, excellent point! I alluded to this in OP. The Thai customs may be less efficient but they are also often less stressful.

However some posters overlook that a more absolute common-sense sometimes applies. If one ethnic group, as a poster mentioned, insists on boarding a crowded car before passengers disembark, can be agree their common-sense/courtesy is sub-optimal?

I made the mistake of starting with a rather trivial example. My post in the earlier thread should be a better example of discourteous parking. (Indeed I posted it there because all the American parking erros in that thread were trivial compared with those we see here.)

In giving examples one needs to compromise between too few (“Oh those are just anecdotes, Septimus, you can find a few bad drivers anywhere.”) and filibusters! I have lots of stories about driving in rural Thailand which are amazing and amusing. That might be fodder for a fun thread, but I won’t start it; I seem to do a poor job of setting up the crucial thread title and OP.

Yes. To counter-paraphrase Alex Trebek, you’ll need to state your question in the form of a comment if you expect more than a one-word answer! :smiley:

One thing that is true is that outsiders often see some aspects more clearly. An interesting thread might be to review things about America that foreigners see more clearly than Americans.
