Well, it does work in the US, it just isn't very helpful. Unless I'm driving through HUMBERSIDE.

2 points: change the "RAC site unavailable" to use $url (sure it won't bite you, but if you cut and paste and leave the +d in ...), what the heck you have the info.
Make the next unless /$want/ a /$want/i so:
humberside
will work too (not just Humberside).

Doubt the US will ever have such pleasant traffic reporting.
