Here's a 'funny' example in the opposite direction. Compare

http://maps.cloudmade.com/?lat=39.583466&lng=-76.129246&zoom=13&directions=39.57989335828052,-76.15070343017578,39.603175259215426,-76.0719108581543&travel=car&styleId=1

with

http://maps.google.co.uk/maps?f=d&source=s_d&saddr=N+Earlton+Rd+Ext&daddr=39.602249,-76.071911&hl=en&geocode=FVDyWwId_gh2-w%3B&mra=dme&mrcr=0&mrsp=1&sz=13&sll=39.582936,-76.100922&sspn=0.093139,0.154324&ie=UTF8&z=13

The Cloudmade/OSM route is about 28 times longer. I expect it's just a
simple missing connection but it make a big difference in the NY to
Washington DC route (1.3 times longer).
