It's not representative because the average ridership is below 2. It's not about how many people can fit, it's about how many people are using it. The car realistically seated at most 2 people. Each bicycle seated exactly 1 person, so 7 people in the same space.

You can fit 7 people in an SUV if they’re all going to the same place. You could say “isn’t that what a bus is?” but a bus has way more space, is happy to frequently stop, is much more fuel efficient per pserson, and is part of a larger network.

That assumes every seat is filled.

Can the SUV go in 7 different directions?

Aside from what everyone else said, not every spot is taken up in that bike rack, and the SUV is still larger than that bike rack.

Depends on the SUV as well. My RAV-4 is considered an SUV, but uncomfortably fits only 5 unless you also want 2 people to squash themselves into the trunk, and it's big brother, the Highlander, isn't much better. My dad just replaced his Yukon (also known as a Suburban or Escalade depending on the brand and time it was made), and that could fit 8 people relatively comfortably, but it's also a bigger car than the one pictured - bigger even than the 4-door Tachoma he replaced it with.

And there is space for at least two more bikes as the leftmost bar is empty.
