|The double rainbow I saw.|
Most overpasses don’t have anything to hang onto if you are getting pulled by the wind, and the one I was under was no exception.
The best response in my case was to stay away from the tornado, of course- I should have driven at right angles away from the thunderstorm. In my case, that would have meant turning around, and probably sleeping in my car, or a hotel room, in Lawton that night, but it would have been the safest course of action. Since I insisted in driving into the storm, the next best course of action would have been, assuming I saw a tornado, to stop the car, get out, and run for a ditch somewhere a good distance from my car, and lie face down protecting my head until the tornado passed. The reason this (very counter-intuitive) option is safer is because tornados lose wind speed as they get closer to the ground- and at the ground level, the wind speeds are zero. The further you get from the ground, though, the faster the relative speed rises. This is the reason to stay out of the car- they’re high enough to guarantee they’ll be hit with very high wind speeds, making you even more likely to suffer injury by getting rolled over (by which I mean tumbled like a child’s toy, possibly being picked completely up and slammed into something), showered by broken glass or trapped inside. Lying face-down in a ditch is safer because debris is less likely to get dropped on you and you aren’t likely to get blown around, but is still a “last ditch stand” that should be your final, desperate option.
