In T Nadu and AP we are already paying 9% first registration Diesel is going to be priced on par with Petrol (like abroad).passenger diesel car prices will come equal to petrol once this happens.Like in Singapore and London and in Europe, Road tax will be introduced and entry tax to enter city centre will be introduced.Odd no regn plate vehicles can drive only on Mon wed,Frid,Sun and Even No On Tue/thursday,saturday,sunday,Week end only driveable cars ( like in singapore ) with less registration charges.Second car in a persons name Double registration charge.If Public transport is improved ( free from Union stronghold) ,every thing can be done.Draconic driving tests and punitive fines will remove lot of bad drivers(and their vehicles) from the road.if nothing is done expect bumper to bumper traffic jam for 4 hours morning and evening rush.Already I can not take the car out of my house in the evening as I live in heart of the city in a commercial area.
