Mind the Gap - Lap by Lap
Mind the Gap is a race course map that was made during a stream where the idea was to make, well, a race course from scratch.
Mind the Gap is the possibly the most basic of race courses that you can make, in the virtual theme, taking a bit of inspiration from the sample map, but giving the basic premise of the map its full potential by adding more turns, extended tunnels, and a smaller bridge to venture across midway through the race.
I personally have not gotten a much better time than around 3 minutes, but there is a platinum medal for any drivers that are faster than 2 minutes and 55 seconds. Are you a pro driver?
