Cause he said he had his head turned and did see the cars in front of him coming to a stop.Why do you people always hijack these threads??????
If we are looking at this for a possible solution to preventing the entire accident and not needing AEB, then by providing an ergonomic change to his side mirrors is a viable solution.
We have all these new technologies to help us when we are distracted or unable to fully be aware of every situation around us. Hence why accidents happen, because they are accidents. If he didn't have to keep his head turn to look over his shoulder, this accident may have been avoided. I linked the video because I had my mirrors set incorrectly during my 10 year driving career and only recently discover this method this year. So I thought I'd shared my newfound knowledge with the great people of this forum =]
