Bradley Wiggins has called for a new law making it compulsory to wear cycling helmets.
He was speaking after a 28-year-old cyclist was killed in an accident in London, shortly after his gold medal win at the Olympics.
Asked what he thought about the safety of London's roads, he replied: "It's dangerous and London is a busy city and a lot of traffic. I think we have to help ourselves sometimes.
"I haven't lived in London for 10-to-15 years now and it's got a lot busier since I was riding a bike as a kid round here, and I got knocked off several times.
"But I think things are improving to a degree - there are organisations out there who are attempting to make the roads safer for both parties.
"But at the end of the day we've all got to co-exist on the roads. Cyclists are not ever going to go away, as much as drivers moan, and as much as cyclists maybe moan about certain drivers they are never going to go away, so there's got to be a bit of give and take."
