"She then looked to her left and then to her right and I had no idea what she was going to do, I thought maybe she was joking about, but then about 30 seconds later I heard some beeps from the oncoming traffic which could see her.
"And she just waved at the traffic and then fell down onto the road. As soon as I saw it I called the ambulance and police."

A free HIV testing clinic will open in a London church on Sunday in a bid to tackle the higher rate of infection in the African community.
Living Flames Baptist Church on Fulbourne Road in Walthamstow will open its doors as part of the Take Action Now campaign by the ActionPlus Foundation.
Cases of HIV among Africans in the UK are 30 times higher than the general population, and ActionPlus believes churches have a central role in dealing with the problem.
It hopes training programmes to educate church leaders and testing clinics in churches can replicate a similar campaign in Ghana.
The clinic, which is being operated in collaboration with Positive East, an east London HIV charity, is opening to coincide with HIV testing week, which runs from November 22 to 29.
The Take Action Now campaign was launched at the Mountain Movers Chapel International in Southwark last Sunday.
"The bible does not condemn people with HIV as cursed.
"It shouldn't be taboo to discuss it in churches.
"It's a medical condition and people need medical help. Prayer cannot bring our health back when we ignore medicine."
