You cannot hold the passenger responsible for what the driver is doing. If that were true, a lot of passengers would be catching tickets.
Now I posted a link showing the actual car at his car show.
From what I have read it's a single car crash...wrapped around a pole.
This from CNN is all I could find...
"The wreck took place about 3:30 p.m. (6:30 p.m. ET), about 300 yards from the office park where the event was held. The speed limit there is 45 mph.
Up and down the road near the crash site were burned rubber and doughnut marks as though someone smoked their tires in figure 8 patterns.
"I don't know if the marks in the road are related to the crash," said Los Angeles County sheriff's Sgt. Brian Allen."
you are speaking strictly from a legal perspective.
Of course we have all entered into a car with a driver who broke a traffic law (driving a few mph over the speed limit, passing a red light, etc).
However, there is a difference between getting into a car with someone who breaks a minor traffic violation, as opposed to someone who is driving 160mph. Most people are not going to stand for the driver driving 160mph without saying something or having the person stop. I am not too sure what Walker did, but I bet he did not make him stop. My bet is that Walker did not try to make him stop.
You have to think about a spectrum. There are minor traffic violations and then there are major traffic violations. This is a major traffic violation, and if Walker was exercising better judgment, he would most likely not be in this predicament (I cant say definitely would not be, but most likely wont). I mean, you have to be pretty freaking stupid not to try and put a stop to someone going 160mph at 300pm. (maybe he did, who knows).
