And, back.in the dark scary days when MIL was still driving [shudder], she could only drive on a set route through their (very small and quiet) rural town. This set route avoided all roundabouts ('they stress me') and any right hand turns in front of on coming traffic ('I just never can tell whether to go, or not').
So, if she offered to drop you in town, so you could have a drink, you had to arrange to meet friends in a pub that was vaguely on her 'route' or face a hike across town.
She also refused to reverse the car or do a 3 point turn. So when SIL started riding lessons I was puzzled why it wasn't at any local stables, but was somewhere 15 miles away...turns out, it was the only stable with a large enough yard for MIL to just drive fully around it, without having to manoeuvre it, or reverse, in order to drive out again.
She also wouldn't ever drive at night, as she couldn't co ordinate steering and dipping her headlights at the same time. On the one occasion, I know of, where she had to drive at night, she took along 10 year old SIL to dip the headlights for her, from the passenger seat.
I was once in the back seat, SIL in the passenger seat, and MIL driving. A pheasant ran out into the road, MIL screamed...took her hands off the wheel and covered her face with them...causing young SIL to grab the wheel, else we would have gone off the road.
There was a huge collective sigh of relief when MIL finally hung up her car keys, for good in 2009.
