My family bought a Civic in 2005, and the only things that have needed maintenance is the engine, gearbox, power steering and it has been in 3 major accidents, even though it's been so many years 220000km. The systems you mentioned are usually very robust and don't need that much maintaining.
Now on to the other things you mentioned, when fuel cars first came, they didn't have petrol stations everywhere, the stations came after the public need for them grew.
And EVs can be easily charged at home, and if I had bought an EV, it would be smart to add solar to my roof as an EV is basically a giant battery. So not only could help me if there was load shedding but also I will get to drive everyday FOR FREE.
This argument is about the rights of the consumer; Pakistan has one of the worst consumer rights. If I want a petrol car or an EV it should be allowed. I shouldn't have to pay bribes and go through shaddy (Haram) methods to go an buy any car I want. I think everyone can agree on, this point.
Now if you are talking about firefighter and paramedic training. Hahahh there is virtually no training for any type of vehicle let alone EVs.
Not their fault, it's the govt, and we should all speak up about such issues.
However because EVs have batteries, they do not ignite immediately, they heat up slowly and keep burning that way for hours. This can give passengers ample time to vacate even with their belongings.
This also helps the fire fighter reach the destination even in traffic such as Pakistan's and the recommended way to treat such a fire is to slowly keep adding water to fire. No special chemicals that are needed to treat oil fires.
Hope I helped clear the picture, if you still think there is something you don't understand, do reply.
Cheers
