Would you ride a four-stage moving walkway across the Brooklyn Bridge? Of course you would! Which is why it's quite the shame that the plan for such a contraption—"Passengers moved from one to another until finally taking a seat on the benches aboard the fastest, which whisked them across the bridge at 16 km/h. Because the system ran constantly, there would be no waiting and little momentum lost on stops and starts"—hatched in the heady days of 1902, never came to fruition. [New Scientist via Kottke]
