That works unless you get caught by one of the "errors" that mapmakers supposedly used to add to help them catch copyright violators.

There could also have been errors in the database of street segments. The database usually only contains the numbers at the ends of each segment, and the rest happens by interpolation. If the numbers are wrong or the geometry is wrong, ridiculous things can happen.

Greetings

Here in Great Britain all the road maps are accurate. All generated by Ordnance Survey. However, street maps were often done by commercial publishers and they did add one or two 'features' to see if other publishers copied their maps.

Many years ago I had a friend working for the Ordnance Survey, who made the observation to map tracks through wooded areas it had to be done with paper and pencil on the ground.
