Dark Blue Cerb going South West on M42 B'ham, 3'ish

[Pete B]

Coming home from a weeks holiday in cornwall, just about to drop off asleep,( not a good idea when your driving an isuzu trooper but you can understand why!) when I spotted you travelling the other way in the 3rd lane, woke me up , got me thinking of taking my own cerb out tomorrow, how I've missed it!
ps. you we're closely followed by a yellow chim, you'd probably passed it earlier!
