I would like to suggest a Freerider - Cameraman edition. For us JohnnyFPV "want to be's" it would be pretty cool to have a simulator to practice following moving targets. Example would be using the existing Forest from Recharge (sort-of) and throwing in a Mountain bike or Having the Rover driving in the Desert scene. New scene would definitely have to be a racecar on a track though. You probably could get away with using the existing code on the recorder and just let the user choose their own screen recorder of choice if they actually want to record. More versions more sales and I don't think this is done yet.
as for @relaxfpv suggestions I do like the idea of assignable buttons/switched but does the driver even support that on anything? As for the Beginner mode I would like the opposite by adjusting tree hits to wipe you out easier. This would be a bit more like real life.
Another suggestion might be to add a little random wind with a level adjustment. I don't think this is too resource intensive and should be a pretty easy add in.
Overall this is my favorite simulator because it is the smoothest I have so if the features bog it down forget it please. Love your work and I look forward to more great release's …………………………………………………..Like Cameraman :)
