Have been playing this with my almost 5-yr old son. He really has been enjoying it but the multi stop corners slow down things a bit too much for him. Therefore to keep it simple I just made all corners 1-stoppers. It really speeds things up by a lot as you rarely need to drop below 4th gear. Not as strategic as the standard corners but more high paced fun for us. A single lap doesn't take as long either which means we sometimes have time for 2 laps.
Quite a fun variant that mixes up your usual gear strategies if you are already very familiar with a track. You can get to see more 6th gear action as well!
