Thankfully not the supe, but my company car a VW Passat, that had just been serviced and delivered back to 20 minutes before, serviced by no other than a VW main dealer, who put new discs and pads on the back! Just got on the M4 up to speed in the fast lane at about 80 and realisied something was wrong started to slow and head for the hard shoulder and wheel came off in middle lane at about 60, thankfully nobody hit the wheel or took me out and I managed to get to the hard shoulder with anybody getting hurt. All this during rush hour!! Scared the s**t out of me I dont mind telling you. Just got home now and realising how lucky I have been, especially has my 3 kids all gave me big cuddles and tell me they were scared for me. Thankfully they were not in the car I was on my own out getting there christmas pressies!
