Oh dear. Was on my way home last night from a mate's house, on the M25 in the Jag, coming up to the M4 exit.
Was doing 70 in the 'slow'lane ready to pull off left onto the slip exit (which is a long slip road).
There had been a previous incident of a vehicle fire on the hard shoulder, with the burnt out vehicle being loaded, but leaving a large wet greasy patch leaking onto the slip on an otherwise dry road.
I took the slip road and went over the greasy patch, and the back end broke away to the right, and then back to the left.
Then me and Jag did a slow 180 pirouette right across 4 lanes, and we ended up facing the wrong way buried in the crash barrier of the fast lane.
I'm fine, but it has stoved the Jag in down that side. I even drove it home, but waiting for insurance to write it off!!
Never a dull moment, and could have been a LOT worse, how I didn't hit anything and nothing hit me I will never know ...
