Driving down to Dorset on Friday along the M4 in South Wales and she asked me to take the next exit (junction 30, Cardiff east) and then take the 2nd exit on the left! That's a bit odd I thought as, 1, it's nowhere near where I need to exit. Just after the Severn Bridge would have done me! 2, the 2nd exit takes me back down the slip road to rejoin the motorway!! Needless to say I ignored her and carried on. Has anyone else experienced this?
