I would guess the most popular mode of transport in Italy is motor scooters and motorbikes. You are simply surrounded by them in every Italian city I've ever been in.
yes i do think the Delhi metro is consuming lots of pollution. as pollution is one of the main causes for global warming, many of the skin diseases it causes many harmful effects and it has to be stopped at any cost Delhi metros be the most suitable and fastest mode for travelling people definitely prefer the metros rather than waiting for hours in the traffic .people avoid taking their cars the cars are the best one to contribute for pollution .hence reducing pollution.
The main mode of transport is rail or bus.
