The next day, I went to Home Depot and bought 2 chipping hammers. Had a couple of extra knives and side cutters (dykes/wire cutters) so put one of each in our car and pickup consoles. In case we need them to cut the seat belt, or, in case I came across someone else in a wreck, I could cut them out, if necessary. Should door be locked or jammed or window up, could use the chipping hammer to break glass to reach in. Side cutters in case belt was so tight couldn't use knife, especially through jagged window. Can always ease s/cutter in and snip snip snip, and free.
