They are efficient but alot of older drivers are truely terrible and really should have hung up the car keys. We do need stricter testing, like being able to see.
Had first hand experience with FIL, and SIL more recently who was driving about with two cataracts that were urgently operated on when she finally went for an eye test. She still cant see properly but is driving.
I believe every 5 year retesting. For everyone.
My wife phoned me yesterday to see if I could come and help a young women driver get out of her car which was laying on its side in a roadside ditch. Granted it's a bad bend, frequently we see vehicles laid in the ditch. My wife managed to get the young lady to climb out of the boot, as the doors had locked themselves. Whilst she composed herself she told my Mrs where she was going. She gladly took her to nearby destination where friends were waiting. On the journey the young lady casually said, Oh I texted my friends that I would be only a few minutes.
Yep you guessed it, the car lay in a ditch a few minutes from her destination.
I hope she's learnt from this life lesson !
