Wow, that's all nuts. Yeah, building more roads never helps. Sounds like a complete redesign is needed, and/or a greater reliance on mass transit.
The roads here in Japan are terrible too. Not quite as bad as there it looks like, but not great. Thank god we have a pretty decent train system.
trains are game-changers. When I first moved to Thailand back in the early 2000's there was no train system in Bangkok and going anywhere was a maddening experience. With the trains now in that city, everything has changed and I no longer hate going there.
