My current plan (obviously open windows if possible, don't drive into lakes, etc.) is to use the resqme spring-loaded glass breaker (my work gives them out as branded swag at conferences, but I gave away hundreds in Iraq/Afghanistan when I worked there too) or glowrhino carbide tip I keep with me. That doesn't work very well on laminated glass (but I'm often in a rental, so I don't know which cars have/don't have it). Failing that, put some rounds into the glass and try to pry it out of the frame. Shooting a handgun in a car with closed windows (especially) is pretty disorienting, I've done it while wearing earpro but never without, but beats drowning. (I'm somewhat surprised the sheriff deputies in the Chao case didn't try this...seems very Texan solution to opening a closed thing)
The technique with laminated glass is basically to make a line of cracks/deformations to allow you to deform the entire panel and pop it out, not to make a hole to go through. Pretty hard to do with a carbide punch, but probably your best bet. Then use legs or body to push the entire window out.
Also, the smaller/accessory windows are often NOT laminated (esp on Tesla), so hitting one of those to let water in and then equalize pressure to GTFO is an option.
