Cambodian Prius infestation

I recently went on a vacation to Cambodia and Vietnam.
OMG, the streets of Cambodia are overflowing with gen2 Prius!!
When we got picked up from the airport in Phnom Penh and the car was a gen2 Prius, I was really excited - like hey this is my car! I suddenly felt at home in this very foreign country. But then later that day, our next ride was in a gen2 Prius. Then I started looking around and noticing that like every 3rd car was a Prius. Mostly gen2, occasionally gen3. Nothing newer than that.
See the attached random photo I took that has 3 gen2s in it. This was typical.
After awhile, it became a little creepy, like a horror movie! Of course, I started to wonder, why are there so many of these cars here? Remember 15 years ago in the USA when there were so many new Prius cars driving around? They were so popular back then. Do you want to know what happened to those cars? Are they in the junkyard? No, apparently many of them were exported to Cambodia, and that's where they all are now. Crazy!
