I love google maps, whether on my phone when traveling, or on my desktop when planning - I would, though, appreciate google providing options for vehicle height, road width, etc when it offers various routes - sorta like the 'traffic' feature where it might highlight areas of the road that are single lane, and overpasses and bridges that might present a problem...
seems like they certainly already have this data, just need to incorporate it into the options drop down list, just like they do for 'No Toll Roads', etc.
