Drivers Education

Apparently im a terrible driver. I thought I was pretty good but my sister tells me Im bad. It seems like every time I drive someones honking or getting mad.
Honestly there is way too many grey areas when it comes to the driving rules.
Just today I decided to cross the intersection on yellow, not exceptionally fast, there was traffic, but enough room on the other side for me. A bus driver come up beside my car and started like pointing and shaking his head. It made me feel so bad. Yellow means Red is coming; so make up your mind!
Anyway I felt really bad but honestly there are COPS to make me feel bad I dont need bus drivers bothering me too. A lady, yesterday, honked at me cause I turned onto the road as she was coming down, she had her flicker on; indicating she was turning onto my street,but no! She turned like five streets after!? You cant do that I should have honked at her!
So I decide maybe ill be more careful. I was waiting to turn but there was oncoming traffic like 20 cars passing, taking longer than usual. A few times there was a moment wher ei could have sped through but maybe they'd hit me and honk so I waited.The guy behind me gets mad cause its taking me too long so he speeds around me aggressively! So I dont know?! Do you be ruthless when you drive or do you be courteous, seems like both get you in trouble. I hate driving sometimes.
