Plan A here is to try and avoid getting caught in such a vulnerable position. Plan B would be to try and drive out of it quickly.

Beyond that, I typically have at least one flavor of OC in the door pocket or on visor. A Glock 23 could be a little large for such, but left ankle carry works well for me with 340PD or PM-9. With both having pretty short barrels, I've also got IWB holsters for each that facilitate carrying at 4:00. With either set-up and seat belt set on my truck, like someone said earlier, I need to lean forward some to draw.
But, since we all know that "Plan A (and even Plan B) may not work", I prefer to have at least one gun securely on me in the event I need to "drive to survive" and/or exit the vehicle quickly.
