If there was a policeman catnapping in the back of the wailing police car bouncing along Islington's Liverpool Road yesterday, he was surely wide awake by the time he had been jolted over one, two, 10, 20, and finally 31 of the "calming" traffic measures along the mile-long stretch.

Lights oscillating as it lurched between the 22 optimistically renamed traffic cushions, nine traffic tables and several potholes, the police car, like every other vehicle on the road, was travelling well over the 20mph limit.

Is this the most humped of the capital's streets? Nobody knows because no one keeps count, but in a borough famous for its hump-happy policies, it's a decent punt.

The taxi drivers, bus drivers and residents think so.

Timothy Scott, a cab driver from Essex, uses the route as a shortcut into the city.

"It's got to be one of the worst, just look at the state of it.

"It's quite a well-used road because it's handy, but every time I get the cab serviced I have to get my shocks replaced.

"They should use other measures. When I was a kid there was a green cross code to keep people safe, what happened to that?"

Tony Muchri, who drives the 153 bus which snakes through the streets next to Liverpool Road, shakes his head as soon as the h-word is mentioned.

"I travel this route up to 10 times a day and I'm in pieces: bad back, bad knees, bad neck.

"I'm looking for a transfer because of the humps. Everyone hates this route."

But as a resident who has got the hump, Robert Pattison should have the final say.

"It is unbelievable and intolerable - if I had a JCB I'd copy that chap who dug up the hump outside his house and get rid of them all.

"It's got to be one of the worst roads in London: every time a lorry goes over them at night it's like a bomb going off. I have to sleep with cotton wool in my ears."
