These vehicles have replaces most of the tempo's which used to rule chennai roads. This vehicles come in different forms and sizes some are three wheelers and some are four wheelers. The moment one comes before you in a traffic it will take forever to overtake these vehicles (I am talking about guys who overtake following traffic rules but for some who care two hoots about rules this is not applicable). They go awesomely slow and will stop or turn abruptly like a share auto. When you overtake these vehicles just have a look at the faces of the drivers. These drivers have a carefree attitude. They also have all the time on earth. They will be in their own world not caring about the ruckus their vechicle is creating behind. Among these the water can carriers are the worst lot.
