"We drive to the limit and then we're put at risk, and it's happened to me every day.
"All people should be driving with respect.
"[Senior drivers] would be much safer if they didn't have others around them taking risks."
Several clients were choosing not to drive, opting to be part of the Government's Total Mobility scheme that offers subsidised taxi services to members, she said.
The research shows seniors are now more likely than under-35s to drive.
"The decline in driving among younger people correlates to an increase in public transport usage," Roy Morgan general manager Pip Elliott said.
"For instance, in the year to August 2003, 25 per cent of all 25 to 34-year-olds travelled by bus within an average three months. In the year to August 2013 this had risen to 30 per cent."
In all age groups except the over-65s, the proportion of the population driving had dropped during the past 10 years.
Nationwide there are now three million drivers, an increase of almost 400,000 over the past decade, but the overall proportion of drivers in the population has declined slightly to 84.3 per cent.
The youngest and oldest drivers cover the least distance on the roads, with drivers under 20 covering an average of 8100km a year, and drivers 70 and over travelling 9600km a year on average.
Those aged between 40 and 44 average 19,100km a year.
Automobile Association Motoring Affairs general manager Mike Noon said he was not surprised by the findings.
An ageing population meant more senior drivers on the road, with baby boomers enjoying greater health and mobility than their parents, he said.
Senior drivers were not risk takers, and moderated their driving to suit their abilities.
They would typically refrain from driving at night, at rush hour or in large cities if they did not feel confident.
"They are more vulnerable so if they are involved in a crash they are more likely to be injured simply because of fragility."
The survey questioned more than 10,000 New Zealanders between September last year and August 2013.
