I stand by my word, ladies and sirs. I did a test today, 20 laps on the "wrong" side and 20 laps on the "right" side, observing the Daytona big jump landing results.
On the "wrong" side, 6 out of 20 landings resulted in backflips.
On the "right" side, 0 out of 20 landings resulted in backflips.
I drove Ria on turbo challenge, using no power-ups, driving the high road above the beach, using all three sets of booster strips from the hairpin turn. A few wobbly takeoffs were observed, but only when driving on the "wrong" side.
I will repeat this experiment with even more laps and record it in two weeks, when I'm back to high-speed internet.
While we're waiting for Grip:
