Visible crew/equipment: After Josh tells Cher she's such a brat, at the start of the next shot which is the first close-up of Cher during the driver's test, just as she says, "I had an overwhelming sense of ickiness, even though I apologized to Lucy," the top of a crewmember's head, with his short wavy hair blowing in the wind, is reflected at the bottom of the Jeep's windshield, directly in front of Cher and the steering wheel. (01:11:55)
Trivia: When Cher is talking to Dionne over lunch, you see Cher's "rival" walk out of the cafe doors with a boy trying to talk to her. That boy is a young Dax Shepard.

Chosen answer: When she says "dual side", Cher is referring to the driver side and passenger side airbags (which are installed in the dashboard in front of each seat), not airbags on the side of the Jeep (aka in the doors).
