There simply isn't enough resources to make them cheaper.
There isn't enough dug out of the ground to supply enough ev to everyone who has a vehicle.
Electric vehicles cannot replace the vast majority of commercial uses.
There isn't the infrastructure to charge all these ev.
There isn't a way to charge most of these ev.
There isn't enough green energy available so we would be using fossil fuels to charge a vehicle so they don't use fossil fuels.
As much as I agree we need to move away from fossil fuels there needs to be a lot more planning and thought before this kind of thing actually occurs.

From what I recall, the efficiency of gas ICE vehicles' engines is so bad (less than 30% energy used) that even if you used a oil driven electric generator to charge a electric vehicles that would still be more energy efficient overall.
It doesn't matter that we would, for now, have to generate energy via non-green power plants, because the overall energy efficiency would still be better (60% energy efficiency) Also, it's far easier to handle pollution in a single place than to have each individual vehicle having their half-assed filters.
People also forget the energy lost converting oil to gas, and also the distribution itself creates pollution

Let's not forget all the inefficiency in the manufacture of those vehicles and the efficiency of the power being generated.

That's what I said. Power plant are far more energy efficient than ICE vehicles (around 60%), and the electric car itself is about 90% energy efficient.

Which would be almost the same as an ICE vehicle? Besides that, electric vehicle should last more than ICE ones.
An ICE vehicle transmission has around 20 moving parts in it's transmission, requires oil chance and a lot of maintenance. Electric vehicles' transmission consists of 3 parts and require way less maintenance.
A good battery also lasts a long time. TESLA batteries average capacity after 10 years of usage is around 90%.
Even the brake pads are better conserved in electric vehicles because of their electromagnet regenerative breaking.

No the carbon foot print of an ev is far higher than that of a conventional combustion engine car, especially when you also factor in the shipping of parts around the world to allow for construction.
Electric was never a good option tbh, the funding would have been far better spent developing hydrogen or bioethonol systems, bioethonal being very close to petrol but more efficient in volumetric efficiency and close to carbon neutral over a 3 year cycle with the added bonus of it being possible to also convert existing petrol vehicles lowering the costs over the next 10-15 considerably. Diesels can also be run on different heavy oils such as peanut oil, lowering their carbon foot print considerably
Edit because u/mjfi4cp2 blocked me.

Hydrogen: Using three times more energy per mile for no good reason

False on all counts.
Lithium is incredibly abundant, and besides that, battery tech is evolving to eliminate rare components like cobalt and shift to sodium and iron, which are even cheaper. Next cones solid state batteries that will be more powerful, safer, and last even longer.
Most EV owners charge at home on standard infrastructure.
Night time load (when EVs are usually charging) helps utilities and actually smooths out grid loads and electricity pricing.

lithium is abundant? wtf

I disagree and would love to read some professional articles that have evidence and reference to fact for what you are saying.
I'm in the electrical industry and we are being told the opposit.
Also charging at home becomes difficult when many park on the street.

Amazing. Every word of what you just said was wrong.
