> CalTrans finally sent ABC7 News a statement later Thursday"confirming" it's their policy to fix broken safety barriers within seven days, or five business days ... but storms delayed the work. As Dan Noyes reported Wednesday, the family told me they believe Walter Huang would have survived, if CalTrans fixed that safety barrier in a timely fashion.

Until the barrier is fixed that part of the road should have some sort of marking to indicate that there is an extra danger there, that's what cones were invented for.

I'm sure a hitting series of traffic cones taking up the space where the safety barrier was could have alerted even a modestly distracted driver to brake.

Plus the genius driver had a number of issues with autopilot in the same spot. He had complaints in with the Tesla dealership that his car tried to steer him into the barrier in that location, prior I believe. Something like 7 complaints filed?

Maybe he was trying to get out of his loan but didn't know the impact absorption barrier had been removed.
