Life In The Slow Lane
The M26 has often been described as the longest slip road in Britain. True, with 9 miles of almost uninterrupted 4-lane tarmac (yes two lane carriageway motorways do still exist), it could well lay claim to slip road status. An argument further enhanced when the motorway is actually closed. So three cheers for the car transporter that caught fire this morning, closing the west bound carriageway. Even more praise for the convoy of juggernauts who decided to 'self-regulate' the traffic slow by PARKING on the inside lane of the London M20 (which was taking the diverted M26 traffic) helping to cause a 4-mile tailback.

M25 J4 > J5 >> A21
Still the above diversion did allow me to sample what has to be the worst and most badly designed stretch of the M25 directly. Between J4 and J5 the M25 goes from three lanes to four. Fantastic you may think, but at J5 it splits into two....two lanes for the M25 and two lanes for the A21, BUT the majority of the traffic (M25) gets filtered out to the Left, whilst the A21 continues at break-neck speed on the right. All the M25 traffic then goes into this twisty descending section, which feels like you've just come off the motorway.
Worse still is that the two lanes of the M26 the come in from your left and then ANOTHER two lanes from the northbound A21 kick in. Coupled with J5a 4 miles on (aka Clackett Lane Services), it all equals CHAOS.
And they want to charge people for driving on this????

Grime and Punishment
Poor day, despite the 100+ trucks parked on the M20. "Big White Van" was one example that comes to mind
