You remember how the Millenium Bridge used to wobble? Well, it turns out that it had nothing to do with designers Sir Norman Foster and Sir Anthony Caro. No, according to a civil engineering report, the blame actually lay with us, the public. Because we weren't walking across it properly.
Apparently the issue with the £18 millon-bridge was that instead of walking in a straight line, people tended to move from side to side to maintain balance. Worse, they all moved from side to side differently.
