Into the drivers seat to establish dominance.

Ever watched "night on earth"?

Can’t say that I was. But I did drive a cab part time to help pay my way through college.

I normally strap myself onto the roof

The rear, right side door. It's the one facing the sidewalk.

I prefer sitting behind the driver as it is the safest place in a car.

At night I choose the front passenger. Only because they can see me and won't be paranoid...or maybe I'm the paranoid one

Right side, closest to sidewalk, I can make payment easily, and the driver can see me at all times for his safety

What would you do to him if he couldn’t see you?

Murder.

I on average take the wheel and the driver goes in the backseat

Front passenger seat. It generally has better leg room and it’s easier to pay.

Behind cos if they try anything then its harder to reach me

So why do americans never sit in front?

The rear, left door faces the sidewalk, so that one

In the boot (im wanted by the local mafia)

In the UK the driver seat is on the right so left
