An 80-year-old Baulkham Hills man working in a backyard in Castle Hill suffered a broken arm and deep gashes after an out-of-control car left a roundabout and crashed last Thursday.
Resident Marisa Giorgi, who has lived on the intersection of Cecil Avenue and Orange Grove for 11 years said this was the second accident at the roundabout — over which people can drive — in the past few months.
The man was taken to Westmead Hospital for treatment and was released on Saturday; his wife said later he was "lucky to be alive".
A Roads and Maritime Services spokeswoman said there had been three crashes at the spot in the five years to June 30, 2013.
But Ms Giorgi said she seriously wondered about that figure.
"I've always said someone would end up in my front yard because of that damned roundabout," Ms Giorgi said.
The vehicle was eventually brought to a stop by her back fence.
"I don't even want to go into my backyard. I'm afraid," she said.
For her part, Ms Giorgi was diagnosed with anxiety and said she had been referred to a psychologist.
She and her four kids, twins aged 10, a six-year-old and 20-month-old, were home when the accident happened.
Mrs Giorgi said the children normally played outside with the dog.
"I am going to fight this 'till it's safe. We have all had enough," Ms Giorgi said.
"People speed through and disregard the give-way signs, drive over the roundabout in an unsafe manner.
"It's not the right area for lights, but it needs something to slow people down."
She said The Hills Council wouldn't let her family erect a fence out front, so they planted hedges, but clearly that was not enough.
A police spokesman said "it doesn't stand out as a particular hot spot".
Describing the incident, he said a woman was driving along Orange Grove Avenue about 4.30pm when she attempted to turn right into Cecil Avenue, lost control of her vehicle and collided with the house, ending up in the backyard.
She will get an infringement notice.
