This actually makes a lot of sense, for a few reasons:
~If you're willing to sacrifice range, you can sell an electric car for very little money. The price jumps exponentially with the energy density of the battery pack, so if you can find a market for cars that only go 50 miles to a charge you can sell them for peanuts.
~Very low maintinence makes them a good idea for the developing world. Villages in Nigeria, Uganda, etc. are littered with the wrecks of internal combustion engine vehicles because having them serviced isn't an option. Electric motors are famously durable and long-lived. Only one moving part means the drive train is extremely simple, and there's no fans, timing belts, transmission or dozens of other parts that can break, as in a combustion engine vehicle.
~Plentiful batteries, and experience with using them. In case you're not familiar with how people in third world nations keep their cell phones charged (and yes, a remarkable percentage of them have cell phones) it's typically with lead acid batteries, salvaged from junked cars. They also sometimes salvage the alternators from cars to build pedal/wind generators with, rather than pay to have their batteries charged from the nearest location with a connection to the grid. At any rate they already have the batteries and understand how to build simple charging systems from salvaged automotive parts.
~Lack of paved roads makes the low speed of cheap electric cars a non-issue. If your electric car only needs to go 25mph, you can get away with a much smaller motor, fewer batteries, and a lower price. A simple runabout powered by "recovered" lead acid car batteries, a 1kw DC motor that goes only 25mph could be sold for about what a used gas scooter would cost.
For those in a position to afford powered transportation in the first place, being able to cover 50 miles a day without relying on gas (which is not always in reliable supply and which fluctates frequently in price) or worrying about maintinence would be a godsend.

Every village mechanic from Azerbaijan to Bangkok knows how to repair a basic internal combustion engine. The reliability of old gasoline Corollas, diesel Hiluxes, or Honda Cubs is legendary.

Sorry to let you in on the news, but most countries in Southeast and South Asia, rural residents have easier access to gasoline/diesel than to electricity - internal combustion generators most often power those lead acid batteries that you're so fond of. And you really have no idea how inefficient pedal/wind-powered electric cars is. How many miles do you think a guy would have to pedal on his generator to go a few hundred feet on his electric car?!?
You seem to have confused me for an environut. I don't care that the energy would come from burning gasoline. Hell, if you strapped that generator to a 2-wheeled trailer you'd have a handy range extender for long trips, but you wouldn't need to haul that weight with you on shorter ones. Unlike an automotive engine, the ICE in a generator can run a a constant speed it was optimized for rather than having to throttle up and down frequently, which means vastly better fuel economy. That's why diesel-electric trains actually use electric motors to drive the wheels, and onboard diesel generators to provide the power.
I wasn't aware that ICE mechanics were so plentiful, but is that really better than never needing mechanic in the first place? When you're offering these things in aid packages, you want something robust that never needs servicing. We can argue all day about what the best power source is, but at the end of the day electric motors don't care how you power them. They're fuel-agnostic. If you wanted to be silly, you could even hook up a steam boiler with a trailer full of firewood or something. Fuel cells? Batteries? Generators? Same diff. Divorcing the energy source from the motor makes any vehicle future proof, as it can be adapted to run on whatever you can come up with.
