Real talk, even though times would all be "around 8 hours", in my Desert Bus run my thumb let off the button and d-pad enough that my finish time was 8:01:10. Even though it's a glorified (and boring) autoscroller, this could definitely be a speedrun. If nothing else, having a "leaderboard" would be a nice badge of honor for those that complete a loop.
I sent him a PM. I'll give him a few days to respond. I can't see a justification as to why a board couldn't be made if I'm being honest. Even IF everyone would be theoretically tied at the top. Frame counting would be super easy, and there are plenty of leaderboards where the top times are all ties. Dragster, NES Home Alone are 2 examples I didn't even have to think about. And again, over an 8-hour run, you WILL lose focus and go off the road or let off the accelerator at least once unless you're hyper-focused (the last 2 hours were awful for me LUL).
I'm not claiming that not having a Desert Bus board is any travesty or anything, but again, as someone that has completed a loop, having a board would be pretty cool. Hopefully we get a response soon :)
