Though a huge company, OLA has failed to organize the drivers of the cabs. As most of the drivers hail from the local town itself, they seem to have pre-known each and every road. The drivers refuse to enter into narrow lanes and by-lanes. As all knows that Kolkata is a old city and the roads are much narrower, the drivers behave rudely if the drop location or the pick-up location is somewhere inside a lane. The cabs are good but manners matter the most as we all pay for the service OLA provides. A big THUMBS-DOWN for the mannerless drivers.
