Back in the dark ages when I was young, my dad and sister went to see a guy at the readi-mix plant about a concrete job. This was out in the country. The guy lived on one side of the road his bus. on the other. Dad pulled in the driveway, and went to the house to talk to the guy. My sister, (circa 2 yrs old) was crawling around on the floor. (1949 Hudson Wasp) Some how she got hold of the column shift and pulled it in reverse. Next thing she's idling across the highway.... and runs into the shop door. It was all in slo..mo.. so no injuries, but if there'd been traffic, could have been bad news.
