I didn't say the glitching makes it more fun - I said it adds another challenge. It would be better without glitches, but I've learned to deal with it by avoiding other drivers. It's just another skill to have in order to be good at racing.
I've gotten to the point where I can strategically tailgate behind players in speedkart, causing their screen to flip out. They usually turn sharply to one side or the other, and almost always kill themselves. It's a rather helpful technique.
