I've played this over in my mind.
The problem is that you are focused on the people in front and at your window. Not the passenger window. I'll bet that the driver never even saw the shooter let alone be able to respond with return fire. Your inputs are saturated.
Your best bet is to:
1. Never drive into a protest.
2. Never stop moving if you failed at No. 1.
3. Keep your head on a swivel.
4. Remember you are at the wheel of a deadly weapon. Use it if you need to.
