Bangkok (Thailand)

The Thai government has announced a tax break for first-time car buyers in Bangkok. Car sales heated up at rocket speeds. Thus, the traffic congestion there has increased to an unprecedented extent. The 50 km distance between Badum and Central Bangkok can be covered in an hour. However, at present it sometimes takes 4 to 5 hours to cover this distance.
