If you value your life, or just that bus crash-less streak you've been on, you might not want to take a ride on the M101. The Post reports that the M101 was the most dangerous bus in the city in 2009, crashing 268 times. The main culprit? Rookie drivers. Veteran drivers know the route is dangerous, and use their clout to drive the easy routes. How else are they going to find time to text? The second most dangerous route is the M15, both for crashes and the rage-filled passengers ready to lash out at the SBS.
