Plot hole: How did Madison handle routine radio checks when she took over the police car? And why didn't the dispatcher notice something was amiss?

Plot hole: It's completely unbelievable that a police officer would sit in the back next to Madison instead of the front, or cuff her with her hands in front of her instead of behind her, or sit next to her with their gun in her reach. This would undoubtedly put the officers in a dangerous risk that they would certainly be more observant of.

Continuity mistake: When the main character is swimming and then bumps into Josh who is dead, in the shot underwater there is a lot of blood, but when it cuts to above the water, there is no blood in the water, and when it cuts back to below the water, there is a lot of blood again.
