I beat up my step dad. Was I wrong in doing so? (Long read)

You were wrong to do that. You need to learn to control your temper cause you get very agitated and very angry way too quickly. I'm suspecting you are 17 - 18 years old since you are learning to drive, get very aggressive, and seem quite moody.
Also, even though he isn't that nice of a guy, it seems as if he does try with you by cooking for you and even taking you driving, so that makes what you did even worse. And, he gave you a lot of time to teach you driving, but you clearly weren't motivated enough to do so cause you weren't willing to go to sleep early, so you can't blame him for that. Also, why does it take you so long to learn driving? It took me 2 weeks.

From his story it sounds like the step-father's issue with him is that he doesn't help around the house (He has a bad shoulder from the sound of things) and shows a total lack of respect.

My father used to bitch all the time about me never helping out around the house. He would bitch at me because I would never mow, take out the trash, rake the leaves, etc... I left it all to him.

That doesn't make him an asshole. If anything, I was the asshole who didn't appreciate what I had. Now I make it a priority to make sure I help out as much as possible and prevent him from having to do too much back breaking work. He is 54.
