I miss my car. I live in a metropolis tho where it has taken me 4 hours in a car what would have taken 30 minutes to walk. BKK traffic is ridiculous. Public transport here already kicks ass (Sky-train, subway, bus system, cheap taxis). I can get anywhere in Bangkok for less than 10 dollars.
For longer distances, buses cost 20 - 30$ for a 1st class seat, take a train for about the same, or a plane for 50 - 100$. I love this place.
I'm sure someday if I'm making a crazy amount of money I'll think about buying a car and getting a chauffeur, but for now I'll focus on buying a house/condo and settle for a taxi.
