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.

I undertand that situation probably better than anybody else. I have only had a license and a car for year and a half. I had to buy my own BEFORE getting my license with the help of a friend to drive with me. I have practiced driving on and off for years(since I was 18) with about 10 differrent ppl. It is tough to find a car and somebody not your family willing to dedicate the time to show you the ropes the whole 9 yards
