Cyber Park 1.5
Cyber Park 1.5 is a trollish track by CyberFighter. It is made based on Cyber Park 1 extending both straights to 20000 Blender units, and has only 4 rescue points. This allows cutting 1/4 of a lap but any mistake makes you lose a lot of time. The whole lap takes about 18-20 minutes. However, the finish line doesn't work.
If you really want to try this and then scream because of spending half an hour into nothing, you can download Cyber Park 1.5 here, you can also use this link with /installaddon command.
