I'm a lefty. There are ways around this - one of which is a shoulder holster. The problem isn't so much drawing left-handed, it's being able to access a gun that is pressed up against the inside of the door. There's not enough room to access it effectively. But a shoulder holster gets you around that, whether you carry it under your right arm, or under your left. If you carry it under your left arm, you can draw with your right hand. If you carry a traditional lefty shoulder holster under your right arm, you can still access the gun easily with your left hand, and shift it if necessary to your right hand.
But that said, don't lose sight of the fact that your best weapon in a lot of those scenarios is your car itself. It will hit someone MUCH harder than a pistol bullet. Consider the possibility of using your car as a battering ram or as a weapon, to put distance between yourself and your foe, so as to give yourself time to access your weapon.

That reminds me of something that came in my mail yesterday:
Yes, I can lean way to the right and draw the gun, but it isn't as easily or quickly done as it would be in a right-side holster......which is one reason why I favor a shoulder holster for longer distance drives.
