Bunch of newb questions

Loading and unloading passengers. It’s like they want to run across a busy road or block an isle? Stop in the middle of traffic?

I didn’t know I would be picking up people from Walmart with groceries. Should my car be empty?

What happens if a passenger damages your vehicle? I’ve heard about some $200 cleaning fee?

Navigating. Should I be using uber maps or Google maps? I worry about tolls?

Thought there were more but can’t remember them right now.
