Laura, I just love this. I am so far behind you - I still get baited constantly and I am going to strive to be like you.
It's funny the car thing - my H had the exact same reaction when something similar happened to my car.
But yes, let go, dont' let their attempts to fight take hold, walk away, etc. I don't know how you do it, I still get the inner reaction of "how dare he!" but I am striving, like you, to find my inner strength, detach, observe, and feel free. I have a lot longer to go than you but I appreciate your support as I work to get there!
