Well, since you asked on

Wednesday 15 August, ITV, 9.00 its
'Robbie Coltrane's B-Road Britain'

this seemingly isn't a joke, here's its write up from said television listing magazine:

'Robbie Coltrane travels the length and breadth of the country sticking only to B-Roads'

This is to commemorate the fact that change has occured since motorways opened 50 years ago.
