Surprising because it's a place not known for having up to date infrastructure nor for being particularly "technophile".
Shouldn't be too surprising because a lot of places that didn't have modern infrastructure tend to skip over intermediate steps when they do get to "catching up".
Mostly doing well because the gasoline infrastructure is piss poor, because gasoline infrastructure is much harder and more expensive than electric to get going.
Not really surprising, several countries in Africa are all in on electric motorcycles and buses, it was just a matter of time for EVs to get more popular
