When I'm driving, my husband acts as if he's in charge. He says he's just trying to be helpful:
Gives instructions (the lights are going green - he says 'you can go now')
On a route I know really well ('turn left here', 'get ready to turn right just ahead')
Operating the car ('change down here', 'signal here', 'overtake now')
Running commentary ('why did you slow down then?')
This one really gets me - he signals to other motorists on my behalf. I don't always see he's done it and have nearly come to grief. (What other driver heeds the passenger btw??) THEN he shakes his head in disbelief in sympathy with the other motorist.
Makes me crazy. I've been driving for over 40 years and I really am OK at it. I'd rather just have a nice conversation while I get on with it.
What does yours do? How do you deal with it?
