At least the bird will not be waiting to target your freshly waxed Tesla.

Though you maye nd up with it's head on your windshield.

These type of turbines work well as vertical axis because the wind can blow from any directions. Here it's only when blowing along the highway. What are they intending, to capture the air displaced from passing trucks?

That picture is at least a few years old. As I recall, it was some student project and yeah, the idea was to recapture energy from passing traffic.

Yeah, I see now that it came from an old (2007) article.

Perhaps vertical turbines in the center would make more sense for such an idea anyways:

Won't that increase the air resistance for the passing vehicles, by keeping the air from flowing along with the cars?

I'd love to see an explanation for what happens (drafting-wise) when you suck up the wind energy on one side of a large truck.

Yeah. seems to me that it would take more gasoline.
