As scary as it looks, you do get accustomed to it.
Everytime I go to India, the 6 hour drive from the airport to my house has my heart racing, but after a week, you really do get used to it.
Asian driving styles habits are really ass backwards compared to ours. It's almost like functional chaos.
They don't use rear view mirrors so much as they use horns. When you pass someone on the side, it is polite and almost mandatory to use your horn to let them know you're there instead of them relying on using the mirrors.
Also, everyone is at any given moment, ready to pass someone, so they always drive more on the middle of the road to have that time advantage so they can merge back into their line while narrowly missing oncoming traffic.
