Vehicle 19

I wonder why many script writers have to make the protagonist looks stupid in order to make the movie looks suspenseful. Why did the protagonist put the gun on the dashboard? Why didn't he tell the black woman that he just rented the car? Why didn't he go straight to the US embassy in the first place? Why didn't he just send the recording file from his phone to the judge & the press? Why didn't he directly charge the phone when the battery was low? Why didn't he answer the black cop's question? If you just want to see a full action car chase, then this movie is for you. But if you hate watching stupid protagonist, then avoid this movie.
