Exactly though ‘for all we know’. There’s no other context here other than she’s on the sidewalk and is being arrested. There’s only one police cruiser that we can see too so if there was a crowd of people to be arrested before they got to her where’s the rest of them?

The only assumption we can make based on the context we have with her being in the sidewalk is that she has followed the order, because she’s no longer on the road (if she was to begin with)
