But the reason for the speed limit could be because of the risk associated with exceeding that speed on that road, and throughout that turn, right?
I haven't seen any evidence where the speed limit was set where it was due to traffic or pedestrians, but I have seen at least one example where the speed was set where it was to avoid being burned alive in a fiery crash.
When coupled with the quote "The law enforcement officials concluded that speed going into a tight curve was too much for Rodas, though he was a veteran race car driver.", it could reasonably be inferred that he was driving a) faster than the law allowed, b) faster than the tires allowed, c) faster than the speed in which the car could be safely controlled, and d) faster than the speed under which the driver could maintain control. None of these are the fault of the car manufacturer, and to me it's crazy to postulate that they are in any way responsible for it. Otherwise, you could extrapolate it out to say that every car manufacturer is responsible for every speeding ticket that anyone has ever gotten - because it was reckless of them to make a car that could exceed the speed limits.
And if they're going to apportion liability, then why don't the apportion it out to everyone that was part of the process, but also didn't really cause them to drive the car too fast and crash it? Maybe the company that laid the asphalt could be found partially liable for not installing a type of asphalt with more grip/traction. Perhaps the person/dealership that sold the guy the car should be found partially liable for selling him the car. And you could find the owner of the tree into which they crashed partially liable for choosing to plant and maintain a tree at such a critical juncture of the turn - they could have know that a skidding car could leave the road at that point in the turn, based on speed, centrifugal force, etc. And the car wouldn't have gone anywhere if it hadn't have been for the fuel that someone chose to allow the guy to pump into this car - it's akin to selling the uranium that goes inside the nuclear bomb.
And yes, I've taken this to the extreme, ludicrous end, because that's what the whole thing is to me - ludicrous. The guy bought a fast car. Paul Walker chose to get in the guy's fast car. The guy drove the fast car fast, and it crashed. There's no one else at fault except for the guy driving too fast, and the guy that chose to get in the car with him. Maybe she could sue the estate of the guy that was driving, but that's it, in my opinion.
