You have to be realistic though. If I'm in the car with the missus and realise we've taken a wrong turn somewhere then my options as unofficial navigator are:
1) Say nothing and hope she works it out herself
2) Say "we'll keep on going this way, it'll probably be alright"
3) Get her to turn around at the safest, nearest point, wherever that might be (might be a way off), and we'll have to make our way back as quickly and as best as we can
4) Tell her to pull an immediate handbrake turn now at full speed and spin the car 180 degrees
1, 2 and 4 just aren't viable options. 4 is as bad as 1 and 2.
I do appreciate though that if you're of a reasonably Blairite tendency (which I suppose I am, within reason) then you're not going to find Starmer's messaging or persona that much of a problem, whereas if you aren't/weren't then you probably will.
