One thing we must keep in mind before talking about the handling is "how long have I been playing this game". The dev team has many months of experience and we're still not perfect. Maybe Zero3Growlithe is the closest to perfect because he spends a lot more time testing the physics.

Point is: SSGX is not an easy game. The tracks are much tighter than on WOHD with little margin of error. You will even have to let go of the accelerator sometimes. It's not made to make your life easy. It requires way more practice than the average WO game.
