They definitely need to give older drivers regular medicals , I think at 70 you have to self certify that you are fit to drive but you don't actually have to have a medical, I'm sure some older drivers haven't been completely honest when applying to renew their licence for fear of having it taken off them. I'm a HGV driver and I have to have a medical every 5 years at age 45 onwards (46 now ) but you can cause almost as much damage in a car if you have a heart attack while at the wheel
