Plot hole? How did K know which car Deckard was in?

Hello everyone. I think I've found a slight plothole. I love the movie, so I am not one of those nitpicker haters, but I would like to know what you think about this.

Near the end of the movie, when K is chasing Deckard trying to save him, how does K know which of the three cars Deckard is in? K chases three cars, and knocks down the ones at the sides, which were flying at a lower height.

My interpretation is K knows these two side cars are guarding the one in the middle, but still Deckard might have been in the right or the left car, as a diversion. Another interpretation could be that K actually sees Deckard through the cars windows, but this is not very consistent with what we see onscreen, where the cars fly at a distance and their insides are not very visible. Even if the first interpretation is more sound, it's still a plot hole in my opinion. One could assume K simply gambled.

Any thoughts?
