Bus-on-stilts from China is awesome, not widely useful

You take the low road—I'll take the 1200-person bus on stilts. Pros: Basic concept—raised passenger compartment that allows "bus" to use regular roads while cars travel beneath it—seems like a fun solution for getting to the faster-than-a-traffic-jam speeds of dedicated rail without, you know, the cost of dedicated rails. Cons: Trying to imagine a city in the United States that simultaneously has the density to need a 1200-person bus and the height clearance to allow something this tall to travel freely about town. Even if you scaled it down to a smaller passenger size, I don't see this fitting under freeway overpasses or even beneath the electrical lines that hover over wide avenues.
