I read the report and found it interesting, though not surprising.
But are there any prospects at all of getting such obvious safety notions into the engineering standards? It's pretty disgusting that peak speed is so valued by those in charge of road design that we are forced to accept the predictable carnage when it would be so easy to do it right.
