Here are a few obvious benefits off the top of my head:

* No local emissions from burning fuel.

* Noise greatly reduced.

* Much less energy consumed (and CO2 generated) per mile overall.

* The car is always topped up when I leave to work in the morning.

* Great driving experience; instant silent torque is very convenient, and hard to give up once you've gotten used to it.

* More space left for cargo.

* Middle seat in the back has actual leg room.

They are much more comfortable to drive. Electric cars kind og just floats where fossil fuel cars struggles at first. If you have charging at home or at work you never need to go to a gas station, you always simply get in to the car (not turning on the enginge) and go where you want. I think those are the biggest two, but I guess it is one of those things you need to try to understand. There are tons more benefits though, like they are less noisy, the lack of a big engine makes the interior of the car more flexible design wise, the acceleration increases the fun factor even at low speeds, easier repairs, they just feel more modern.

Right-now benefits: Dirt cheap to charge (especially in countries where fossil fuel isn't subsidised). Cheaper taxes in several countries. Not contributing tons of CO2 and various toxins to the environment every year. Less dependency on a secondary energy distribution network.

Possible benefits: Simpler engines should lead to lower production costs, more reliability and simpler, cheaper repairs.

Lower maintenance costs, less mechanical parts, more safe because there are more crumpling zones, less noise and cleaner because there are no emissions.

Lower maintenance requirements and costs.

About 4x cheaper to charge/fill up, and about 3x less maintenance costs.

Plus all the "nice" features of EVs like rapid acceleration, no noise, feeling super-modern/futuristic, etc.

None now, but I can envision that vehicle simplicity relative to the gas powered one (simpler engine and no transmission) will eventually mean lower price and lower repair costs.
