Boris Johnson's Narrow Escape

Speed bumps are a load of bollocks, if they really want to control speed over a distance down a road then they need average speed cameras, more expensive yes, but at least its not fucking up vehicles and causing ambulances to have to take diversions for spinal injury patients etc due to risk of death!

It's not as clear-cut as that, James. There is a clearly measurable reduction in casualties where vertical deflection measures have been introduced. My own personal criticism is that I find it deplorable that we should have such problems in civilising traffic that we even have to jettison the concept of a road or street as a smooth surface on which passage is comfortable and efficient.

There are certainly 'higher-order' measures that can be taken, and although they are often expensive and untested, are being applied more, with some successes in places.
