Since there is almost no public transport option for now, you can consider relying on company provided transport for your commute to work. A lot of the companies provide real nice, comfy buses/vans for pick-up and drop-off. The only downside is that you will have to stick to their timings. But, I do know of people who are able to make this option work for them.
The next option would be a 2-wheeler. If you have been away from India for a while, riding a 2-wheeler may or may not be possible for you. Now, if you are going to be the dare-devil to try a 2-wheeler amidst this traffic, then the next deterrent is going to be the pollution levels, especially at peak hours. The smog will make you squirm on your 2-wheeler seat. My husband was one of those that considered a 2 wheeler for his regular office commute, mostly because he was going to be saving a little bit of time. Obviously, your ability to maneuver is far better on a narrow vehicle. Also you occupy much less space on an already crowded/narrow road, and in turn will help the insane traffic in your own small way. But after the initial few days of observing the traffic patterns, he just gave up the idea! :)
When I see all the bike guys halting at the red-light and balancing their 2-wheelers with their feet on the ground, I worry for the safety of their feet. One of my cousins was at the red light with her feet on the ground, and an auto just went over her right foot. Thankfully, the damage was minimal. Since all the vehicles are just inches away from you or your vehicle, the thought is scary. What if it was a bus that had gone over her foot? And of course, there are still others who have had many a fall from their 2-wheelers. Not to mention the inconvenience during the rains.
If you want to use the autos for your everyday commute, you will have to again cover your nose for the entire to and fro journey because of the vehicular exhausts. Whenever I take an auto, after a few kilometres I notice a fairly distinct smell in my hair; all the exhaust fumes taking their toll! The exhaust fumes also make me feel squeamish. The other factor of course is the meters - you may not want to see the auto meter reading all kinds of numbers, since most of the meters are rigged.
A sea of autos. Notice how our rear-view mirror is broken (bottom left corner of the pic).A simple mishap when one of the other cars was very close to ours!
On R2Iing, buying a car will be one of your crucial decisions. The good thing is, there is a fair amount of choice for cars in the market, and definitely so for small sized cars. 'Cars' is an exhaustive topic and I will cover all the options available, over a period of time. I will write about the available small cars in the market when I write about cars next. I will also write about the available cars based on their sizes and their prices subsequently.
An R2I Tip: The traffic is really bad; can't stress enough. See pic below. If you are sure about your R2I plans, then the one thing you can already do is to slowly start losing your attachment to your cars/roads there. Things will not be the same here and preparing yourself for it in advance helps. And when you do get stuck in traffic here, you will have the choice of not letting it affect you. That way, YOU still have the power! And you can take that time to think about your true reasons for coming back. :)
