SPECTATE
Watch the lap. Learn the decision.
Watch a saved run
Use SPECTATE to follow recorded rivals. NEXT changes the run you follow; STOP returns from spectating. The drive pad and steering display replay the recorded controls when the lap has them.
Look for one thing
Watch a braking point, the end of a slide or where BOOST begins. Then try that one change in your own lap.
Read the setup
A replay can show the perks that run used. Understand the combination before expecting another car to follow the same line at the same speed.
