I don't mean control by an unauthorised party or hacking of EV, charging infrastructure, plugs and sockets - although this is also a concerning and growing threat.
Hackers and malicious actors aren't that bothered about 'saving the planet', they would rather harvest your credit card details from the charging point. Having said that, there are ideologically driven eco-terrorists who would rather you didn't breathe to save the planet, so there is that new emerging threat.
The main threat is from your government, having the ability to switch off your transport options at their will. Just as they have the ability to manipulate the information on the internet now, monitor, track and control the data you see on your mobile phone, track your location, listen into your Alexa devices and mobile phone and cameras. They have the ability to control EVs, charging points, smart meters, all from the comfort of a heated and air-conditioned central office located anywhere on the planet.
Given what is happening in Oxford and Canterbury with their 15 minute cities, one of the next steps will be to restrict the mileage you can drive in your EV, then either pay additional fees to drive further or once you have reached your mileage limit, the vehicle is switched off until the meter clicks around to the point when you are allowed to drive again - the possibilities for control are endless.
