Changing lanes has become a lot more more predominant in the last few months again, I see it happen in about 50% of my journeys through the tunnel.
Bull
Serious, I don't know if we've had a lot of foreign visitors, very few foreign tunnels disallow lane changes. I don't go through at peak times, about 9:45am and 4pm once or twice a week. Some of the lane changes I couldn't even understand like getting themselves stuck behind a slower car not far from the entrance - very surreal. On my last three journeys through the Queensway Tunnel I saw people change lane each time, I don't think I've ever seen it in the Kingsway.
one of whom assaulted me not that long ago..
S**t
Guy got far too close (10ft-ish), I indicated for him to pull back, he came closer (6-8ft), I gently slowed down to 20mph, he got closer still (like under 3ft at times), went through over half the tunnel at that speed. Far end I got stopped at lights, my window was open about 3"-4" and he managed to pop me, skinny bloke!
I reported it to police, they visited him and he came clean straight away, had no previous and swore it was out of character (things going on at the time etc), police said they thought he was absolutely genuine. I chose to let him off, its on record, if he makes a habit the police will do more, if it was a one off then no harm done,
I'm not into affecting people careers, insurance etc for a one-off temper tantrum.
