Let's say you are driving solo in your car, at night. Badguy number one get's out of the passenger side of a car in front of you at a traffic signal. For the sake of arguement, all exits are blocked by other vehicles in traffic and sidewalk obstacles in the form of lightpoles etc.
BG#1 has walked behind this car, moving across your front to the left, and appears to be going to continue between adjacent stopped vehicles across the road - but makes an abrupt left, out comes a crowbar and he gesters and shouts at you to "get out".
Well, no. You are not going to get out at all. And he hasn't really given you but two seconds to do so anyway, and he shatters your driver's side window. Despite the fact that you "were ready for it", the speed with which he swings the bar against the car, the blow and noise, flying glass, have a certain shock value.
That's it though. You can not escape at this stage. The light has gone green, but BG#2 isn't budging - and the driver in the car to your immediate left is
thinking about "helping" you - and isn't moving either, despite the first honking horn behind.
A split second later BG#1 is going to try and brain you. He has this down pat now - no more "arguements" with stubborn drivers. If they do not comply right away; brain them, yank the door open, pull them out, get in and go.
He didn't tell you this, but you were making ready to draw anyway when he left the car, headed back and across your front. When the window shatters, in the second and a half that follows, where a conscious decision becomes action, BG#1 is about wound up for another lunge.
..... And I will speculate that in this hypothetical, and 1001 similar.
most people will be better served using a point shoot. With either hand through the window opening, or righthanded through the windshield if needed.
Even outside of a motor vehicle, the radical change in facing direction, posture and attitude might consume too much time in meeting a deadly threat depending on the circumstance.
I do think point shooting is more likely to be useful in engagements at shorter distances, and in shorter time frames between initial threat awareness and the actual decision to shoot. And a fast handling revolver or pistol with better point, balance and handling qualities is going to facilitate things.
