alt Hacker NewsFor my parents it was 65-70 when I noticed and started to become very concerned for their ability to drive safety. At 75 now, my dad at least only drives during broad daylight but even so he can't maintain a safe speed and does barely half the speed limit, then complains about tailgaters not liking his "retired lifestyle" (which is his personal excuse for driving slowly, when in reality he lacks the skill to keep up with traffic, which is very dangerous in my view...)
It's a danger for sure, I think for many the best they can do is limiting their driving as much as possible to 'safe' roads. With elderly driving slowly it's more a problem of ruining their car when they crash than endangering lives. Wish there was a better solution for all of them.
