I think its a glitch because the wall is completely flat and even touching it slightly in that certain spot (even a very gentle scrape) will cause it to throw the zone ship violently into the other wall, it doesn't seem like that should even happen so I refer to it as a glitch.

Also I've had the case where the ship becomes airborne and it only happens to me above 120 zones, I think what's going on is you know how the zone ship anchors itself to the track? Well the same point on the first left-hander the track dips and sometimes the ships own momentum from exiting the first corner can throw its nose up as it travels down the track inclination but still anchors itself to the track, but if the speed is great enough this momentum can throw the ship into the air resulting in that problem. Colliding with the inside wall can also cause this at high zones.

Saying that my definition of a game glitch is:
A problem/mistake in the game that causes it to behave in a manner that was not intended by the programmers.

The problem I mentioned is therefore a glitch in my eyes, but this problem is open to interpretation
