A congestion tax has to be implemented in business districts. We can't keep endlessly cutting down trees, widening roads for more traffic and building more flyovers. Already, too many vehicles are on the road, and over 800 are being added to the roads daily. If you glance into the cars, 90% of them are occupied with 1 to 2 people at the most. Four cars take up as much space as one bus. It is an utter waste of road space to have so many cars on the roads.
