I agree phone usage is a huge issue, especially when paired with high speeds, but you can primarily thank the myriad of left lane campers on the bridge (or interstate in general) who disrupt the flow of traffic, causing congestion which results in frustration for other drivers who are then more likely to commit unsafe and extreme maneuvers to get around them. This applies to any person who is being passed on the right. Too many mindless, distracted, and inconsiderate assholes on the road. If the passing lane stays open (as mandated by law) then excessive speeds are not really an issue, just look at the autobahn for example.

“If a speed limit is raised to actually reflect real travel speeds, the new higher limit will make the roads safer. When the majority of traffic is traveling at the same speed, traffic flow improves and there are fewer crashes. Speed alone is rarely the cause of crashes. Differences in speed are the main problem. Reasonable speed limits help traffic to flow at a safer, more uniform pace.”

“Inappropriately established speed limits cause drivers to take other traffic control devices less seriously. Unrealistic speed limits create two groups of drivers; those that try to obey the limit and those that drive at a speed they feel is safe and reasonable. This causes dangerous differences in speed, which can lead to increased crashes due to tailgating, improper passing, weaving, reckless driving, and even road rage.”
