Thing is, fastest lap around their track was a minute-20something. The 'budget' car is usually around 1min~40. That's a lot of time to add to this track.
I made a version on my own and was doing about 50sec lap times in the UF1K, so I'm not sure what can be sone with the current 'blank' lots we get to work with.
On that note, is there any way to make a blank, all new course, or is that something only the developers are allowed to do? Can we request tracks? I wouldn't imagine a 1mile x 1mile square lot would be too much
