I live in Houston on I-10, and due to a huge environmental/safety push they lowered the speed limit from 70 to 55. It was a joke, the highway is built for speed and it has excellent lines of visibility and intelligently designed merging sections, and they make you crawl down it.
The highway may be built for speed, but the cars are not.
Standard cars can survive a front-end collision at about 50mph, and much above that they start to fall apart.
Cars are absolutely designed for speed, and if the highway in question was too, your argument falls apart. In order to have a 50 MPH front end colision in 70 MPH traffic, you'd have to have one rogue car either going 20 MPH or 120MPH. You're arguing against a scenario that simply does not happen with any kind of regularity.
Deadly collisions have to do with difference in speeds, the actual speeds are irrelevent.
