That idea kind of sucks, IMHO.
First, your solution involves committing a crime, which kind of negates the fact that is even a solution.
Secondly, if you remove barriers/signage that is preventing harm to drivers/pedestrians, you can be charged with some serious crimes. Not too long ago, some college kids stole a 'Curvy Road Ahead' sign, and some cones. Some tourist got killed on the road, and the moron kids were charged with manslaughter.
So, uh, good luck with the cones. See you in 5-7 years.
