Let them curse.  We had a little snow last weekend, just enough to make things slippery.  Some nitwit in his little "batmobile" (black firebird? camaro?) thought he was above the laws of physics and started careening and pinwheeling all over the road, taking out mailboxes and hedgerows along the way. The look on the drivers face as he went spinning past me toward his doom was priceless.
The sap ended up embedded in a shrubbery, no injuries to life or limb except for a possibly deflated ego.
