Yep. As I lay dying on the ground, bleeding from every orifice, my organs and bones crushed to a fine pulp at the blunt end of a BMW X7 going 50mph. I will reach for my gun and shoot my assailant.

Yep definitely a real plan that solves real problems. /s

[edit] Or was the plan to prevent the collision in the first place? As I see the driver coming for me, murder in their eyes, I will smoothly draw my weapon, shoot the driver through the windshield, leap into the air and sail smoothly over my assailant's steel battering ram, executing a perfect three-point superhero landing as my fellow pedestrians cheer.

Was that the idea instead?

I'm not specifically advocating that everyone carry guns -- I was just responding to the phrase "that's how you get shot". Entitled drivers should recognize their own mortality in the event that they threaten pedestrians with a gun.

But I do prefer your scenario instead.
