There is a higher proportion of elderly people in the south-west of England than the national average, and some here see driving as a lifeline.
In Bodmin, 130 older people meet weekly at the town hall at an Age Concern social group. Some drive to get there.
Widower Reg Harris, 85, said giving up driving would "absolutely crucify" his lifestyle.
Alvin Trevenna, 88, added: "I wouldn't be able to get anywhere, do anything... I'd just as well sit in the armchair and wait to die."
Drivers can refer themselves for an older driving assessment by Driving Mobility at a cost, but referrals from the DVLA, police or NHS are free.
The charity said more than 10,000 people aged over 70 in England underwent one in 2024 - 0.2% of drivers of that age.
The local road safety partnership Vision Zero South West wants more public awareness as well as tighter regulation.
It said 176 drivers aged over 60 were killed or seriously injured on Cornwall and Devon's road network in 2024.
Chair Alison Hernandez said: "We want to protect people's lives because it is absolutely devastating when this happens to people and their families."
Asked what could be done to support older drivers who felt they had no choice but to carry on because public transport often was not good enough in rural areas, Hernandez said her office was planning to run a campaign "to educate older drivers on how they can be at their best behind the wheel".
