I think that there should be a big oval raceway, similar to Daytona raceway. There could also be something like high speed ring in gran turismo. Could someone PLEASE check out my YouTube channel. Rigsofrodders. Thanks
How about a demolition derby arena, there should be a game mode, demolition derby. Cool to see a Gavril D15 hit a Ibishu Covet at around 8km/h a few times...
A car durability test track maybe? Maybe that feature is allready implemented, if so, then its already cool
A figure-8 track like this would be fun (yellow arrows are showing the driving direction): (imported from here) The grey rectangles are ramps that can be placed in upward position, towards the center. The colored rectangles are signs which are placed above the track, to show the right direction. For example, when you are at the red curve, you must head for the red sign to get onto the blue curve, etc. The yellow-black ones are exits and must never been taken. Only the ramps at the exits should be placed upwards, because otherwise the cars will be locked up at the center square. By changing the signs, you can make some variations like these: (imported from here) (imported from here) (imported from here) It can be a lot of fun to do some races, banging or derby's onto this track. I only wish I had the tools and skills to make something like this. It also will only work if there are other AI cars running onto the track (AI can be discussed in this topic).
I think we all forgot something important, SNOW! About any type of map with ice and snow on the road would be awesome to see
