Can I cut in front of people at left turn lanes so I can go first?
Are you serious? Don't you think it's rude to cut in front of people?
It's more convenient for me, and I don't care about causing a commotion.
Cutting in front of people while driving is a dangerous thing to do. You should be polite and respectful to other drivers or else you can anger people and potentially end up in dangerous situations like a car accident.
I don't care about the safety of others. I do want to save time.
It might not save time if you get in accident and have to wait until the police handle the accident. Just be courteous to the other drivers and leave early if you want to be there on time.
