Crash prone 'modern roundabouts'

[kalvado]

I'd personally much rather someone doing three times the speed limit plow into a rock than fifteen people.

What if the person is a bus driver carrying 15 people?

If a bus driver carrying fifteen people plows into fifteen people instead of a rock, then that would be a total of thirty.  So, still better.

Social darwinism is, of course, not without merit h but is generally considered out of fashion.
In the case at hand, if more socially acceptable concepts are to be applied, 3 casualties  about $20 million - should be enough to fire a few people from DOT, hire some real engineers - even with recent $100k surcharge for H1Bs -  and rebuild approaches and the intersection from scratch using proper design. Moreso potential 15 people crash.
