So I'm 50 and DM is early 80s and DF is 87.
I went to visit them today - haven't been for a couple of months and is permitted in a caring capacity. They live an hour away.
DF is a rubbish driver, has always been really, always wanting to overtake is kind of jerky driving, just not great. He likes to drive and pre covid always drove the couple of miles down to the supermarket carpark to buy a paper every day. He can do this fine, and has maintained some local driving through the lockdowns.
However pre covid they used to come and stay with us. DM is now saying - privately to me only - that she doesn't want DF driving on the motorway to us, doesn't think it's safe. She can drive, but DF is an awful passenger, prone to shouting at other drivers and getting in a rage and DM doesn't like driving with him as a passenger.
He's now talking about wanting to visit us once they've had their second vaccination and travel around Scotland restrictions are lifted ( I'd really appreciate if we don't get into conversation about what is and isn't allowed because of Covid). DM doesn't want him to drive, but has not said so directly and is pretending it's because of covid. They almost had a bit of an argument in front of me about it.
We'd happily come and pick them up and bring them to ours or do all the visiting, but DF would question why.
I really don't want to tell DF he shouldn't drive, I feel it's up to DM. As I say I'll happily do the ferrying once they're in the position to accept it. I'm an only DC btw - do I have to tell him ?
