I’m happy to report that Wikipedia seems to have dropped the ‘m.’ prefix, and finally detects the device capabilities instead.

This might be true perhaps; but the crux of the matter is that I shouldn’t do more than the traditional human-oriented escaping of the addresses, which relies extensively on plain and friendly backslashes, instead of devilish and time-consuming machine-produced percent-codes.

Remarkably, apparently either the server or the client replace backslashes in Markdown links with forward slashes, which is completely bogus and nonsensical.

The correct link is https://en.wikipedia.org/wiki/Racetrack_(game)

Also interesting that you’re the first person to raise this issue after two hours and ten upvotes.

There’s a pen-and-paper game called Racetrack, in which people can move a certain amount according to acceleration/braking, turning and inertia. It simulates the physics of actual racing remarkably well, better than many video games. There are both web and mobile implementations of the game.
