My 25 km one way daily commute for the past 10 months has meant covering a swathe of Bangalore's suburuban areas. A common observation during this time has been seeing 2-3 BMTC buses broken down every day. This includes buses across the spectrum. Ordinary buses ranging from old to the relatively new JNNURM ones, Janti Vahanas (trailer buses), Volvos, Marco Polos etc.
