alt Hacker NewsIt's a complicated policy. What about if you're travelling in France? If someone gives you directions do you want it to not be shown on the map because you call it one thing? What about Canada, where part of the country would want the English Channel and the other La Manche. I get why showing two names would help a lot.
Sure but you can leave some of those up to local nuances - like in Canada maybe they show both. In the US maybe they don't since we only call it the English Channel.
But I'd say that it's probably not a big deal anyway because how often are you going to run into such a scenario, and even if you do how would Google/whoever capture a lot of informal names for things? A little bit of confusion is fine too anyway.
