"That's enough, really," Edward was already delighted to hear Juliet wouldn't tell the police. After all, it wouldn't be easy for the investigation to reach him, as long as Juliet kept silent about him.
Why hasn't she arrived yet? Juliet was getting impatient, suspecting the person in front might be deliberately driving slowly.
"Do you even know how to drive? There's no other cars or people on the road now, so why are you driving so slowly?"
Juliet's outburst made Edward, sitting beside her, nervous as well, fearing he might get dragged into her tantrum.
It wasn't that the person in front was deliberately driving slowly; they were just too tired. People need to sleep, hence they were driving carefully and a bit slower. But hearing Juliet's accusations, how could they dare continue at such a pace? So they drove a little faster, but no speed could satisfy Juliet.
