I'm assuming here that, from left to right, S Mathilda Ave has a "right-turn" lane (Lane 1), three "straight on" lanes (Lanes 2, 3 and 4), then two "left turn" lanes (Lanes 5 and 6). (The white car second-from-right appears to be obscuring a left turn arrow painted on the road, correct?)
This being the case, my ideal position there would be sitting on that solid white line in between Lane 4 (second-rightmost blue car) and Lane 5 (rightmost white car). I'd want to be to the left of everyone going straight, such that when my light goes green, that position will naturally take me out wide of the cars turning left, putting you neatly onto your arrow on El Camino Real.
'course, as you'll most probably realise, the skill here will be getting into this start position in the first place, but nevertheless that is the ideal position.
Next time you take an aerial photo, would you mind waiting until all the cars there are different colours? It'd be far easier if I could say "between the red and the gold cars"!
