But why does a woman who once owned an MGB and admits she loves speed want to turn Greater London into a 20mph zone? Alex Eckford caught up with the influential Green Party member to find out what she has in store for YOU.

"I've recommended a 20mph speed limit for the whole of Greater London. There are some roads where it wouldn't be appropriate - and only these exceptions would be marked," says Jenny.

"I'm not against speed - I love speed! I used to drive my MGB as fast as I possibly could. I understand it. But the more I've learned about road safety and road deaths, the slower I drive."

A proposal for a 20mph London is just one of a number of controversial ideas London Assembly member Jenny Jones has for the Capital's motorists.

"I think all bus drivers, van drivers and taxi drivers should have sessions on the road on bikes - and should be trained as cyclists to understand how frightening it is to ride a bike on the roads," says Jenny. "And if they can't ride a bike properly we could find a multi-ability bike for them."

"One thing I really want to get across is that motorists need to obey the laws of the road – in all different areas – speeding, parking and general driving behaviour – parking in the wrong place, blocking road junctions and so on, the quality of life would be so much better," says Jenny.

A Green Party member since 1988, Jenny has become one the country's leading campaigners for road safety, and is one of two Green Party members on the London Assembly.

As road safety advisor to London Mayor Ken Livingstone, Jenny spends her time speaking to people about the issues she feels passionately about, and then reports back to her boss. "We disagree on a lot of things, but basically he lets me go off and do what I want."

"You'd be amazed how supportive people have been, even about the plan for the 20mph zone. People just want to see less accidents on the road," says Jenny.

Jenny sold her beloved MGB 20 years ago, and hasn't owned a car since moving to London in 1991. So how does she get around the Capital?

"I cycle three times a week and take the bus on the other days. I think it's important I experience the transport system first hand," says Jenny.

Another of Jenny's controversial ideas surfaces when I ask her what she would do about the amount of traffic on the road.

"We need to reduce the number of cars on roads - and the way to do that is to reduce the amount of road space. It's the future. The government is pushing for the expansion of the roads - it's all nonsense. What we should be doing is making the prospect of driving less appealing. Traffic would go away because it would be impractical to drive," says Jenny.

Jenny was recently named one of 200 'women of achievement' for her work, and was invited to Buckingham Palace for lunch with the Queen. Prince Phillip had something he wanted to ask the Green Party member.

"He said 'You know what's wrong with your Green people? You never give anyone else any credit.' And I had to admit he was right, although I didn't say it. Since then I've tried to be more welcoming, and talk to people from companies like BP, an idea I wouldn't previously have entertained."

One question remains - will Jenny be running for mayor?

"I might be throwing my hat into the ring," she says. "The Green Party would need to nominate me first."

As I leave radio station LBC call Jenny for a live interview about transport issues. She's a woman whose opinions are much in demand.
