The driver should do better job at responding to the passenger, he can simply replying with 'umm' I don't mind, but not silent treatment for the whole trip. Even the call to appoint pick up location he talks too less.
I told him specific turn for my preferred route and he missed it because he didn't confirm it with me. Also partly because he was busy playing/listening to chat with his stupid walkie talkie app while driving.
I don't mind a little bit of careless driving, or an evidence smell of smoke inside. That's why he still got a three, but just be less rude that would be great.
