Yes, it is cheaper. Compare MPG/savings vs Opportunity Cost/Acquisition Cost, you will see.
An older mustang, jeep or pick-up will run in just about any reasonable condition of repair. Maybe not perfect, but good enough to get you home if needed.
Try that with a more recent vehicle with multiple “sensors”.
Crank sensor off a bit because cold/hot/wet weather? . . . you’re sunk. Temp sensor off because of corrosion? sunk.
Just like Grandpa, pour some vodka or “hooch” in an old car and it will fire right up.
Can’t do that with no electric car.
I could get any car made before 1972 up and running by myself.
I'm keeping it in "stasis" at home. :)
