Speeder fighting back in the wrong way

I don’t understand a few things about this character and I don’t plan on trying to, but simply enumerate them”

First, I don’t understand why this guy would ride without a shirt, nor a helmet.

Secondly, I don’t understand why he even fights back as he is guilty as charge.

Thirdly, why would you go to court dressed like that and have the attitude that he has?

And finally, if you care that much about your bike, why trash it?

I know I said I won’t look for answers, but they simply pop up. So it’s either idiocy or the quest for audience, but most likely both.

P.S. I still can’t stop laughing.
