Here's the reverse scenario.
I was driving in my car down to Binley the other day and, whilst the M6 motorway was busy with all three lanes not far off nose to tail

, it was moving along briskly (I was in the centre lane doing about 70mph).
Next thing a guy on a bike goes whizzing by filtering between the second and third lanes.
Now I filter when the opportunity arises but not those sort of speeds. Just crazy and gives us all a bad name if you ask me
