We do not have the money to do preventive maintenance as the transportation system is underfunded. This leads to roads and buses turning to crap.

Politicos all want the worst roads fixed first leaving little to no money to maintain the halfway decent ones. This table explains what I mean: http://techtransfer.berkeley.edu/new...-4/prevent.php
