Would you undertake here ?

Absolutely, I often use the spare bit of road in front of the white line to place my bike, as long as it's not on a pedestrain crossing obviously haha. I've learnt all the traffic light phases on my commute so I know how long I've got till green so I never actually stop.

Don't see why not.After all it's just a line of stationary traffic asking to be ridden round.You don't have to do it at 90mph of course.

Me too. In fact I do almost the identical thing at a junction here. I make sure that I'm just enough infront of the vehicle to my right so that he/she can see me...and I make sure that I'm first away when the lights change. Once you've done it once, you'll never queue again...probably!!

Of course, caution to be observed at all times but I'm sure your aware of that (this line is the 'get out clause' bit).

Yep i do this everyday but carefully of course

If I was familiar with the junction, which you are, then what you waiting for? Your far more likely to get caught up in low speed 'nudge off' queueing for the RHS lane than you are likely to get caught out jumping the queue! There's very little that is going to beat you away when the light change, so get ahead and stay ahead .The One caution for me would be meeting a chavracer or execgti who wants to race.... Let em' have their victory, but watch your mirrors in case you get shuffled out of the deck....
As far as I'm concerned, we have very little primary safety in terms of protection, so use your power to stay OUT THE WAY

I do similar every day. If I get to the front while its still red then I swing across the first car, I don't think I'll ever get in bother for being a tad over the line (and most cars don't go up to line) but that way the car knows I'm there and I don't have to race them. If lights go green on my way up then I start signalling and find a gap to move in to.

There's only one junction on my commute where I usually just queue, I'm going left, the right hand lane is for right hand turn only, most folks in left lane go straight on so its a but tricky if the lights go green and you can't find a nice big gap. I've been known to ride up the inside in the gutter, but thats not much fun.

Yep, I didnt buy a bike to sit in a queue of traffic. As others of said as long as you exercise caution and be aware of muppet lane changers I dont see a problem, especially if you are familiar with the road layout.

If I'm on the bike on the commute home I do this every time. Ride up on the left hand (traffic free) lane, but as you get to the solid stop line swing the bike so it's pointing right, that gives you a head start to 'pop' out in front of the car on the right.

do it cautiously, and you've just added afew more years to your life because you aint sitting in traffic every day.

Without doubt, yes. Simple as.
