My own conspiracy theory

An article at the BBC talks about the rapid rise in Chinese manufactured electric vehicles:

With China accused of selling electric cars at artificially low prices, the European Union is widely expected to hit them with tariffs this week.

The BYD Seagull is a tiny, cheap, neatly styled electric vehicle (EV). An urban runabout that won’t break any speed records, but nor will it break the bank.

In China, it has a starting price of 69,800 yuan ($9,600; £7,500). If it comes to Europe, it is expected to cost at least double that figure due to safety regulations. But that would still be, by electric car standards, very cheap.

For European manufacturers that is a worrying prospect. They fear the little Seagull will become an invasive species, one of a number of Chinese-built models poised to colonise their own markets at the expense of indigenous vehicles.

China’s domestic auto industry has grown rapidly over the past two decades. Its development, along with that of the battery sector, was a major component of the “Made In China 2025” strategy, a 10-year industrial policy launched by the Communist Party in Beijing in 2015.

The result has been the breakneck development of companies like BYD, now vying with Tesla for the title of the world’s biggest manufacturer of electric vehicles. Established giants such as SAIC, the owner of the MG brand, and Volvo’s owner Geely, have also become big players in the EV market.

Last year, more than eight million electric vehicles were sold in China – about 60% of the global total, according to the International Energy Agency’s annual Global EV Outlook.

Here's a conspiracy theory I have been thinking about for months:   maybe the Chinese government requires all electric vehicles made there (and especially those destined for foreign markets) to have a software kill switch - so that once they have flooded the Western market with reasonably priced electric vehicles and they want to do something controversial (*cough* invade Taiwan), they can punish the West (if it fights back) by remotely killing all electric vehicles in a software update.   (And they will be clever - the update won't be an immediate kill - otherwise those who first lose their vehicle could warn others not to update.  No, it could just be set so that they all stop working on a certain date.   Perhaps an anniversary important to the Chinese.)   Or, now that I think of it - could the update make the explode-y batteries actually explode?  

So, if they have (say) 20% of the total American vehicle market, that's potentially an awful lot of disruption for a country so reliant on vehicles.   

I wouldn't be surprised if someone else has come up with this idea, but I haven't read it elsewhere - yet.   So, for now, I'm claiming it as a original conspiracy theory.
