Rivals left bends and car speeds differed
What the user saw
On web, rival cars could steer off the road on sharp bends and miss a checkpoint. On mobile, the same car could have a different cruise speed for the player and a rival.
Why it happened
Web rivals aimed at a distant checkpoint and had to touch a small target, while mobile used separate speed formulas for players and rivals.
What the real fix did
It steered web rivals along the road and counted crossing a checkpoint line, then gave mobile players and rivals one shared car speed formula.
