Just a couple pointers:
1. Please include a depot
2. Any spline that causes sound issues, do not use until there's been a fix for that problem
Im not nit picking but its not cool not starting in the depot (if you wish to) and i've not heard of a city not having a depot at least a drive from the main routes.
Keep up the fantastic work all, if someone could relay this in German and any other language for our friends, would be lovely!
