Not always of course, but I dont understand this reasoning. For every example you give, one can make up a different one where stopping would yield a better outcome. I do believe though that if we took literally all possible scenarios and weighed them by the probability of them occuring, the results would show that a stopped vehicle is safer than a moving vehicle whose driver can not see.
