you can not compare a 2 vehicle accident to an intentional, planned event of mass destruction,
one is an accident, the other is planned, and intentional, completely different........good try though
because it's already safe as it is......history has proven that......
i will use very conservative numbers here, actual numbers are probably much higher,
lets say an average of 30 vehicles pass through this intersection per hour, so one vehicle every two minutes that would be 720 vehicles in a 24 hour period or per day,
720 x 365 days = 262,800 vehicles per year
262,800 x 20 years = 5,256,000
so that means 5,256,000 vehicles pass through the intersection in 20 years (again, conservative numbers)
there have been two accidents there in the past 20 years so we now divide that number by 2 = 2,628,000
so that means there is one accident for every 2,628,000 vehicles that pass through the intersection
the odds of being struck by a bolt of lightning are 1 in 960,000
so that means you are OVER 2.5 TIMES MORE LIKELY to be struck by lightning then you are to be in an accident while driving a vehicle through this intersection,
that seems pretty damn safe to me!!
