Presently, Prince William and Kate Middleton police escorts are crossing only a few minutes before seriously injuring a 83-year-old widow in terror.
Irene Mayor, 83, has been in intensive care because it has hit 300 meters from her home on Monday afternoon.
The new artwork shows a royal pair of snowmobiles that seem to accelerate at the junction, as the convoy travels through southwest London.
The witness who shot the video believes that the passer-by in front exceeded the 30 mph speed limit on Wandsworth High Street.
He added: "I have heard that everywhere there is a lot of police officers, and I looked down to see what happens I think there is a problem, because the sirens would be better..
"I know the speed limit is 30 km / h, and I felt that the leader was going faster."
There is no suggestion that the rider is the one who participates in the accident.
"YOU CAN NOT GET"
Irene remained in several bones and her condition is said to be serious but stable after a midday crash.
Her sister Joyce Shore, 86, said: “His age is a concern in the hospital. Irene may not get through this.
Joyce said his sister had been in a pelican crossing when the rider was "distorted" and hit her when she returned from shops in East Sheen, southwest London.
The Duke of Cambridge was driven by a black Audi A6, where Kate was in the passenger seat when they returned to Windsor for an event.
Police passerby said to have been the wrong side of the road in front of traffic.
But one witness claimed he "drove it completely". They added: “It was like the police chilling. There is no reason to go so fast.
"TAX ON FUTURE HERE"
The other one described that Irene rotated her feet after being hit and hit her head on the ground.
Louise Rawlinson, 41, who works in a nearby cafe, was one of the first places. He said, “Irene spoke, so it was a good sign. I was on the floor with her for about 30 minutes.
"He had blood in his head, but said:" I'm fine. I'm not hurt. Get me up. The officer who hit him looked gray. He was so shaken and visibly upset.
“He knew he was doing something, but it wasn't his fault. He had cut him accidentally. He didn't even fall.
“Irene's daughter was in shock. At one point he stepped back and dropped the police wheel. That's why it was on the floor.
Wills and Kate just got to know about the accident when they arrived home. They sent flowers and a note to Irene and offered her a visit.

An independent police officer is investigating a collision.
But Irene's sister Joyce has demanded more stringent rules for royal bucks, saying, "These motorcycles are so crazy. We can't remove them because they consider people safe, but keep them straight for good."
“All this zigzag is not necessary. They must not get tangled or run fast because they don't get anything about it. It kills people.
