Why do motorbike riders in Siem Reap not know how to turn left?

Rule is that you are responsible not to hit them, you see them, they don’t. It's a cultural thing, I think. In Cambodia, it's more about avoiding hitting someone than following traffic rules. It's not about being right or wrong, it's about being safe.

I think I understand why motorbike riders might be doing this. It's probably because they feel like stopping and waiting for a break in traffic is too inconvenient or time-consuming. They might see it as more practical to just veer into a break in traffic on the oncoming side, even if it's not the safest thing to do. It's not just a Cambodian thing, though - I've seen cyclists in Paris do the same thing when they don't feel like stopping at a red light.

I had a similar experience with a tuk-tuk driver recently. He was making a left turn, but instead of waiting for a break in traffic, he veered into a gap in the oncoming traffic a half block early. It was pretty exciting, to say the least. I'm not sure if it's just a matter of not knowing the rules or if it's a cultural thing, but it's definitely something to be aware of when driving in Siem Reap.
