Will preface with this with the fact that I do roughly 90% of the driving, especially if it's longer distances and will only ask him to drive if I'm tired etc.
He is so totally oblivious to everything on the road, he will quite happy bumble along at 45/50 on the A303 on the single carriageway bits with a huge line of cars behind him. We're currently on our way back with our 11mo, roughly a 3 hour drive that is going to take 30-40mins longer just because he drives so incredibly slowly. It's taken me 30mins to get screaming baby to go to sleep and as soon as he wakes he's going to be screaming again. If I were driving we would be home by now.
He is constantly braking with no need - will slow for a junction before he can even see it, does 40mph in 3rd gear. In the time it has taken me to type this, he has managed to take the wrong turning despite only needing to remain on the same road.
Sorry, needed to rant, going insane, baby has woken and we're listening to the same song (the only song that calms him) for the millionth time and we're still miles from home. Sometimes I wonder if this is weaponused incompetence so I won't ask him to drive in future.
