Don't know if this constitutes a Controversial post but one of the London Boroughs is actually taking out Speed Bumps, cycle ways, bus only lanes and making parking the car easier. (doing away with traffic calming measures!) and finding traffic flows better through the borough!
Can't get to the actual story but
http://www.timesonline.co.uk/ and the search for speed humps will get you there (you can't copy the site, can only print it out).
Hooray for the removal of speed bumps - I detest those humps which jar the spine even at low speeds and Bus Lanes (empty for most of the day) and Cycle Tracks on the road (Cyclists use the pavement(sidewalk) most of the time as most pedestrians know to their cost!).
Does anyone think these things on the road are a good thing for anyone?
And while on the subject - Isn't it time that Learner Drivers were taught the etiquette of good driving as well as the theory and practical. (First signs of Road rage or aggressive driving means an immediate FAIL) - and

no need for speed humps and other measures.
