Those are really good examples of barriers to speech reading from the way different speakers express themselves.
The case of "The car driven past the barn crashed" shows a chance for confusion even in a correct sentence, but it takes time to see the kernal sentence is "The car crashed."
Worse are mangled sentences we see, like "He found a dollar walking home" and "Taking off from the Albany airport, the sun rose reddly in the east." I must have puzzled over that last one for five whole minutes. It just didn't make sense! Ha ha ha.
