Yes, yes, yes, I know, this isn't a "roller coaster". In the ride designer on Android you can build more than just the coasters, when you do, your gokart tracks go through a "simulated" run and complete the stats. Obviously then you can export and import to your PC. The "track" designer in RCT doesn't allow for other than coasters, so in-game when you build a gokart track, you have to wait until you get a full amount of drivers before it will run. This can be frustrating if you have 31 (max) carts, as guests usually won't go on something until the stats are done. As far as I know, there's no "test" for gokarts.
Any suggestions would be welcome.
