The new luxury buses that Pallavan has introduced are awesome! I can now travel from Adyar to Valluvar Kottam at Rs. 7 or Rs. 9 and most of the times I have got a seat! I personally hope AC bus services are introduced at least along select routes. I traveled in one such bus in Bangalore and the journey was extremely comfortable! (Of course, in Bangalore you may just take an auto instead :)) I wouldn't mind paying for it as it would definitely be cheaper than the 70 I used to bargain for an auto home.
These luxury and semi-luxury services are beneficial on another count as well. Clearly, Chennai was not designed to handle the quantum of traffic that it is handling and the situation is bound to get worse. However, the Indian mentality is such that we have to buy "an own vehicle" because it indicates financial stability! Therefore, if good quality, reasonably priced public transportation services are available, it may ease peak hour office traffic.
Interestingly, meters are slowly, albeit very slowly, coming into use in Singara Chennai. I think the onus lies on the consumer's side to insist on the meter. Of course, the danger is that for the rest of the journey the driver will patiently educate you on the economics of running an auto in Chennai. If thy nerves are made of steel, or alternatively, if you don't look like a Tamilian, you could make him put the meter and still survive the journey!
The new Hyundai Police cars with lights at the top are such a welcome development. They give you an impression that the city is in good hands. Definitely more re-assuring than those old jeeps. In fact, in most Tamil movies the Police will be shown arriving after the hero had done whatever needed to be done. Maybe the jeeps were the reason!
However one pet crib with Chennai has been the lack of majestic, awe-inspiring architecture. Another requirement would be top class, well maintained public libraries. But anyway evolution will take its time.
But whatever may or may not happen, it will always be "Madras Nalla Madras!" :)
