Arshyam'ji - you have not yet seen the depths of babudom creativity yet. There is RTO!! And green tax!! And restrictions on commercial vehicles! And then there are desis who try everything to avoid RTO etc!! But yes with electronic toll collection, separate lanes for trucks etc are parallel enhancements that will ease congestion. Core is removal of octroi/entry-taxes etc., the avenues for dog-biscuits are minimized and smooth flow of goods & services will enable growth in economy. Per nomura., the trucking efficiency will increase by 18%.

Here are the implications of GST.,
1. Sitting in Bengaluru, Kerala - I can purchase blocks of granite from Mangalore, AP - and ship them to shilpis in ChengalPet, Raj and Udaipuram, TN. And from there I will ship the finished goods to major markets in Delhi, Ahmedabad, Chennai and other minor markets. This is done online., all I have to do is have prior contracts in hand and payment by bank on receipt of goods. Here the goods and services are both moved! The shilpis in ChengalPet, Raj have continues work contracts based on season and fashion and they do not have to move out to market their services. The granite from blocks (goods) come to their doorstep.
2. I can take a shipment of low-grade wheat from Punjab - send it to Bengalure, Kerala and process it into cattle-fodder or beer malt for markets in S. India.
3. Take Jute from bengal and send it to kerala, take coir from kerala and send it to madurai. Take dates from Gujarat and process it in Mah and send it to chennai and export it further into Indo-china. I am sure introducing date shake in Thailand will be a novelty!
4. Organic food from Manipur sold in the bazaar of Bengaluru, Kerala. All one has to do is put in a shipment on the train and take it up and directly sell it into the market! With computerization, the forms are also computerized - just stick it to the shipment!
So with GST., within a year-or-two I see an explosion by 30% in economic activity. To me that translates to 1.5% of growth in GDP. That is zoom-zoom-zoom Indian economy!
Hence hold on to your pants (or whatever)., a region which is size of Europe is going to be integrated! This is the biggest news so far this year.
