I like the idea of drilling a hole in that bar and putting a screw or some sort of latch on it. Something that will hold it open, but will be easy to remove in case of emergency. I definitely don't want to mess with the function of the window.
What I was thinking of would not require removal in emergency - just push
it open, same as normal. Since the nail, screw, hitch pin or whatever
is OUTSIDE, it would not interfere at all.
For those worried about nails and tires, a blunt pin or nail with
point ground off is always an option..........
Other folks have mentioned a clamp of some sort. Placed OUTSIDE
the window frame, that would also be a fine solution.
