The lack of independence when driving is off the table is incredibly hard. We were so lucky my mom’s neurologist told her point blank that if she kept driving she would kill someone. He didn’t mince words. She reached into her purse, handed me the keys, and when I got her back home, she told my dad to sell her car. I did a lot of chauffeuring early on but thankfully she accepted it gracefully.
A friend’s mom was super angry and they had to basically disable the car (removed the entire battery because after it was disconnected the first time she called road side assistance to have it jumped). Eventually they told her it needed to go to the garage and it just “wasn’t ready” ever again.
