I don't know its good or not cause this cars are more smart, but cars on gasoline are more faster, so what do you think about this?

Electric cars runs at a satisfactory speed. Unless you are joining a race, don't use this. But if you are just gonna use it just to joy ride, personal service amd other stuff that doesn't require high speeds, then you can go with e-car. Also, it has many benefits rather than disadvantage compare to a regular gasoline cars. Though there there are setbacks, these are insignificant and will not affect you so much.
