Try to avoid situations that require intense braking, but every now and then someone will cross to close in front of me and then slow down, and that is on Freeway with 70 speed limit and I am going 62 just to avoid that kind of interaction.
Once I was going about 30 in a 45 approaching an intersection, my light was green, had been for a bit. As I approached a car hurtled across the intersection running the red. I did not come to a full stop but managed to reduce speed enough that she was able to clear the intersection in front of me. When we got to our our stopping place (can't remember if it was a campground or a WalMart) I indulged in a double dose of my favorite adult beverage, after we got everything picked up.
