Actually it doesn't matter at all, how many percents of the planet are
tagged with a certain tag, it is sufficient that the tags are present
in the area you are interested in ;-).

Btw. I recommend to add source:maxspeed as well (sign, country:urban,
country:rural, etc.) and tag all roads with maxspeed (and then mark
implicit maxspeeds with source like suggested in the wiki).
