The question is different. Why we are running these big vehicles on crowded roads? Is there any alternatives?
Yes there are. Please see this video.

RORO means Roll On Roll Off, where loaded trucks are directly carried by railway wagons to their destination. Konkan Railways passes through tough terrains of India. There is NH-17 passing through same route. Truck drivers find it extremely difficult to drive loaded trucks through ghats, undulating surfaces, narrow roads and poor road and weather conditions.
Yes this is the right way. Why 50 drivers driving 50 trucks separately. Lets connect all of them and run by one driver. It will help in saving fuel, reducing tear and wear, avoiding driving effort, reducing congestion and accidents, increasing speed, reducing pollution etc.
For transporting goods on road it will take Rs 6/- on road, Rs 1/- on rail and Rs 0.60 by water.
