The opening of the drive to the airport is a shot over the hood of Ballard's new car.  We have already seen this shot earlier in the film, immediately after Ballard’s accident.

Ballard's slow acceptance of not simply what had happened to him, but the new potentials it offered, is illustrated by his revisiting the previous accident in unexpected ways.  As Remington notes, he has bought a car, but it's the same car as before.  One can suppose this wasn't due to the safety features, but rather was based on residual memories of their potently accidental encounter.

The conversation between the two characters is punctuated with Remington leading Ballard.  For example, he says:  "You haven't told me where we're going."  To which she replies, "I haven't?"  This question suggests that he ought to have known, that she's trying to wake memories within him of events he hasn't yet lived.  It's almost as though she's chastising him for not remembering a pre-destined encounter at the airport parking lot.

Ballard constantly plays with the seatbelt across his shoulder.  While it had kept him alive, it is clear at this point that he's not grateful.  Unlike before, he seems to resent the safety it provides, that it might prevent him from experiencing some unique event, limiting his possibilities, a cold fabric prophylactic. 

We see Remington fasten her seatbelt almost as an after thought.  She too seems indifferent to the safety feature.  Eventually Ballard pulls the belt aside. 

They only briefly allude to their accident, and then through the breaking of stereotypes.  Remington is dressed in a white coat, and Ballard muses that perhaps it's not appropriate dress, and not likely to convince people she is in mourning (which clearly she is not).  Remington snaps back:  "I'll wear a fucking kimono if I want," leaving us in no doubt over her feelings on the matter.

Still, Remington does not have to wait long for Ballard's lust to take hold.   At a point in the road that looks suspiciously the same as where their accident had taken place, they have another near miss.  Remington grabs at the wheel and eases the car into the kerb.  Finally giving up all pretences, convinced that this new experience would finally push Ballard over the edge, she immediately says:  "We're close to the airport garage."  All the while smoking on a pre-coital cigarette.

To this point Remington has been patient with Ballard, more self-aware and ready to go to the next level.  Ballard on the other had appeared to be struggling with what he was feeling, trying to understand it but hesitating.  After this new incident however, he no longer holds back.  Instead, he drives to the airport garage where the two of them commit a frenzied sex act.
