Question related to the legality of filtering, apologies if this has been done to death elsewhere but have you seen the number of hits you get back when searching for filtering!?!
Dual carriageway, stationery or very slow moving traffic (around 10-15mph), if I'm filtering in between them, am I technically 'undertaking' the vehicles on my right and therefore passing illegally (or at least not in line with the Highway Code)?
I arrived next to a police car at the lights this morning (on the inside lane) after filtering for about 1/2mile and neither of the occupants appeared happy/impressed to see me sat next to them
