We have an EV and I figure we will save about $5k or more per 100,000 miles on the fuel costs, but that savings is flipped to a loss if I had to use fast charging all the time. But I'm using $3.50/gallon gas in that math. In Laos gas is almost double that, and electricity is much less than in my math. I get $0.07/kWh at night, but average residential in Laos is $0.031-$0.004 per kWh, so there's a roughly 4x relative advantage based on those price structures. Google says public charging in Laos is between $0.11 and $0.16 per kWh, which means someone using public chargers there would likely still be saving money over a similar gas vehicle.

[I asked google for those prices, so my estimates above are only as good as what Gemini gave me]
