I occasionally watch Adventures with a Purpose, they are on youtube, they use there skills to try and bring closure people who have missing love ones thought to have been lost in their cars underwater.
I bought this from them, its inexpensive and I drive by 20mi bay often and thought more so during the winter it would quiet easy to slide off the road onto the ice and down through it.
