Ouch!!! Glad to read the part that they only sustained minor injuries. But daggone....it obviously coudl have been MUCH worse not only for them but for the ones in the oncoming lane of traffic.
I watched it several times and judging by the number of white lines that pass by in the video and the time, the tractor trailer that was filming was traveling about 71mph. That would put the motorhome's speed somewhere around 75-80mph at the rate of takeover. Way too fast in my humble opinion....
What's the formula for calculating MPH based on the dotted lines?
Very rough calculations, but by my count I saw 35 white lines in 13 seconds. The standard for white lines on federal highways are that there is 10' of paint and 30' of space in between, making my calculated travel distance based on 35 white lines and 34 spaces to be 1,370 feet. That means that in 13 seconds of video from the time the video started until the truck started to slow down the truck traveled 1,370 feet. Speed =distance/time. According to an online calculator, that puts the truck doing about 71mph. The RV's speed was a guess based on the rate that he overtook the truck. Again, my best guess.
