What are the problems associated with extending routes? Is it to do with file size or memory restrictions? I have noticed the length of routes that I own only extend to about 30 miles (as the crow flies) but on Sand Patch for instance after going round all the twists and turns the travelled distance is around 50 miles. So is the limit a case of the total area that can be covered in square miles, or are the routes developed in a linear way? I would pay good money to start at Paddington and drive to Bristol Parkway and beyond.
