I'd say that the electric vehicle will have better security of supply... it's extremely rare that electricity is off for more than 12 hours, but petrol/diesel supply scares are more common. Moreover, having a generator, it's possible to charge an EV given a few gallons of fuel, but it's not possible to fill up a tankful with access to the National Grid.
Well, if you've solar generated electricity …
Apparently there are EV conversion kits for some vehicles.
Eventually S/H EVs will be cheaper and the LiFePO4, while not the highest capacity Lithium is long life, cheaper, less likely to go on fire and less toxic than other Li techs. Newer EVs use it. The patent has also expired.
It does add weight. A smaller EV might have 40 kWh of battery and a larger or longer range EV maybe 60 kWh. Based on a standalone 2560 Wh battery that's about 300 kg to about 450 kg. However the electric motor(s) based system weigh less than conventional engine and gearbox etc. Of course a full tank of fuel might be 120 kg, but it gets used up.
But for longer range vehicles synthetic LPG made in a sunny climate from water, waste carbon and solar power may make more sense. Oddly it's less wasteful to transport bulk LPG long distances than electricity, unless a superconducting grid becomes possible.
Solar is the only viable way today to utilise fusion power or cleanly run an EV in many countries. A steel roof (corrugated or other) is the simplest roof to mount and you can set them on the ground if you have the space.
Bifacial panels can be vertical as a fence or on top of a wall, or be car-port or conservatory roof in themselves. They are a 1/4 of the price they used to be and PV panel life is allegedly x6 to x12 what it used to be.
