I'm surprised that on a sportscar board with experimented drivers some would have such a simplistic view.

Sure, we could all go at 90km/h on a highway and have a few less accidents, why not 60 even better, at 10km/h we would be like bumper cars, no real accidents at all. But we can't do that obviously because the more you reduce the speed of traffic on high speed transit ways the more you are going to impact other things, like productivity, communications, etc. 

The point is that accidents on highways are mostly not due to speed, but rather distractions and driving under the influence, so decreasing speed limits further does not have that big an impact as lay people think while it has detrimental effects that they don't see, but this is not politically correct for our populist politicians, enforcing stricter speed limits makes it looks like they are doing something while also being very economically profitable with speedtrap enforcement, win win.
