The problem with the gauges needs to be investigated by an auto electrician. With the fuel it appears there is a problem with the pick-up in the tank under cornering when the fuel is being pushed to one side. It could be the pump or the filter inside the tank.

Demos are not generally abused; they are mostly driven normally with reasonable care, often under the supervision of a salesman.

You’re worried unnecessarily, and besides, the car will still be covered by Ford’s warranty if it happens to have a problem.

The blades are supposed to flip over when they change direction at each end of their sweep to prevent them doing what yours are doing. Your blades are not flipping over.

The key sends a code to the car to unlock the doors, and also allow the engine to start, as it turns off the immobiliser. Modern security systems make it impossible to hotwire a car like in old Hollywood movies. The best way to get into a Ford Ranger if you lock your keys inside is to call a locksmith.
