I recently saw a meme which showed us how a person with electric car is using trailer and electric generator who work on petrol to charge his car 
This type of cars is great but only for short distance if you try to take a trip to another country what you gonna do ? The same thing this guy from the meme did. Probably after some years the manufactures will invent this kind of engine who will make thru a long trip but for now I'm standing with the petrol cars.
Exactly ! Let's wait a little bit longer to buy one of the upgraded cars who will make it to the next country or state or just over 1000km This type of cars is great but only for short distance if you try to take a trip to another country what you gonna do ? The same thing this guy from the meme did. Probably after some years the manufactures will invent this kind of engine who will make thru a long trip but for now I'm standing with the petrol cars.
