My father is very elderly, and I’ve noticed he has a hard time getting in and out of my parents’ car. I was researching mobility tools online and came across “car canes.” They are inserted into the loop striker of car doors to give a person leverage to get in and out of cars (see image). My question is if using such a device could damage the striker? I think it will help my father, but I don’t want to give him something that would damage their car. He is quite skinny/light-weight BTW. Thanks!
