Other mistake: When Eve runs into the BMW from behind, the guy slams into his steering wheel. When you are hit from behind, you will slam backwards into your seat.It happens twice, the third time the airbag deploys and stays inflated (real airbags deflate in a second, they are not balloons).
Continuity mistake: During the driving sequence on the mountain road, the foliage shown is inconsistent. For example, when the guy in the BMW cuts Eve off and yells at her through the passenger window, orange autumn leaves can be seen reflected on his windshield. Shots outside the vehicles immediately before and after this shot show only evergreen trees in the area. After this, when Beamer Guy is shown talking on his cell phone, shot from inside the vehicle, the trees seen outside his driver-side window are significantly different than those shown in shots outside the car.
