There is just one of this type of bus that I have seen at the bus station. I believe this bus will not be successful as most Karwa buses travel through narrow streets and thus cover larger areas of the city which is convenient for bus users. It could only be used on routes where the roads are wide. Yes, it would no doubt be able to carry larger number of passengers and would be very useful on certain routes during Fridays which see a heavy rush at the bus station.
