Got me thinking about the red lights on the commute to/from work, I've got 14 (8* in the morning, 6 in the afternoon).
Of those, 6 (3 each way) are "jumpable", the rest, absolutely no way, not at the times of day I do that route.
One of those "jumpable" lights is at a junction, and is actually safe to jump if you are going straight on. No reason to though, apart from being lazy/wanting to save a bit of time. 4 of them are non-junction pelican crossings, so again, if there's no pedestrians crossing/approaching to cross, perfectly safe, but actually only save you time.
There's one though, which is a crossing as well, that I'd say jumping it is safer than not, oddly enough it is the only one that I do jump.
it is this one.
If the crossing is clear, and there is a queue of traffic waiting at the light, then yes, I'll jump it*, because that bend tightens as you go round, shifting you out of the cruddy bit of bike lane, which the cars & vans routinely encroach on as they take the corner, too.
Thing's that'd stop me jumping that light, simple, but an ASB on it, so I can filter up the queue and put myself in front of it, so the 1st car can't overtake me while I take the corner, but further along, where it straightens out & widens.
*if the crossing is being used, I'll wait till it's clear and cruise over slowly, and if there's only one car waiting I'll not bother, why aggravate someone when it's as easy to let them get in front as you pootle round
