Elderly / sick drivers

I’ve just parked up outside my house after coming back from work and watched an elderly woman who is extremely un-easy on her feet and who can hardly walk even when holding on to her car get into her car and drive off with what sounded like full revs.

I cannot comprehend how people who can barely walk are allowed to drive and control vehicles using their limbs that basically don’t work.

Don’t get me started on the slower response times neurologically let alone physically.

Make it make sense please 🤣🤣
