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? 
Perhaps we see in the coming years, the streets are crowded with these electric cars or solar cars, if these cars prove their efficiency and environmental friendliness without polluting it, in my opinion technology will be able to make these cars successful, but I think one of the negatives of this electric car will be the high price of its batteries.
