What a fun idea!
I think you nailed the theme with this one.
And holy cow, the music slaps hard (reminds me a lot of the music from OpenTTD, which is awesome). It gets a bit repetitive though.
The controls are a bit clunky (especially panning on PC) and the game could do a better job of communicating what the different road types do. Also on the real maps (which is a very cool idea in and of itself!), I found it hard to see the goal. You can navigate to it using the controls, but it would be cool to make it pop a bit more regardless I think.
But all in all very nice and I had fun playing it!
