One of the best I saw was a guy "driving" an old Vauxhall on the M25 just before the M4 turn off when all the lanes were full of traffic but moving at around 60mph. Geezer was wandering around a bit but holding his position about 3 feet behind a white van perfectly, seemed to be fiddling with something like string then proceeded to use it with both hands to floss his teeth !!!!
Next best was a **** on the M23 who had a mobile phone in one hand and an electric razor in the other, admittedly the traffic was light at the time of this incident so his weaving across all the lanes was only of minor irritation to other road users.
Still, at least neither of them were over the speed limit so I guess it must have been safe enough innit ???
