But that's assuming you don't crash your car, veer off the road, lose control, as a result of being hit by an exploding foreign object, FIRST.
If an egg hitting your car will cause you to run off of the road, you should surrender your driver's license and never again should you get behind the wheel of a motor vehicle.
I can't imagine how you react to serious events that commonly occur when driving.
Maybe you need a push cart or a bicycle if you are so easily addled.
