Are you sure Mexico is accurate there? I feel like that line would hit Alaska. (I didn't do any actual research on this, just looking at a map and visualizing a straight line between Japan and Philippines)
Perhaps I should have been clearer in terms of what the question means. If you kept on travelling at 46 degrees (and kept on slowly changing direction while moved to maintain the 46 angle) you wouldn't reach Mexico. However if you left KL at a bearing of 46 degrees and kept on walking in a straight line, you would stop travelling at 46 degrees but you end up in Mexico. The quiz is based on the initial bearing rather than your continuous direction
I suspect it's more just that this kind of line is extremely unintuitive for people because of maps. In 3d space, it makes a lot more sense that the straight line "reflects" (slowly curves along the Earth's surface) and starts going back south, rather than continuing on to the northeast. In 2d space it would have to actually reflect at some point for that to work.
It looks to me like there *might* be a tiny arc in which you could barely skirt the Babuyan Islands and Cabo San Lucas/Colima and hit somewhere near Manta, Ecuador. Sadly Google Maps is not accurate enough over that long of a distance (or, that precise of an angle) for me be certain.
Without the Babuyan Islands existing, I'm fairly sure it works (my best attempt goes through the northern bits of Calayan and Panuitan), so if those tiny islands manage to stop it, I'm also impressed.

KL : 3,2299127 ; 101,5703764
Manta, Ecuador : -0,9596030 ; -80,7694933
The line is pixel perfect west of Mexico and of Calayan Island in the Philippines.
