If you had your choice of fuels for your car, what would you choose and why?

I'd prefer non of your list. I am looking forward to the time that it will be posible for us to drive car with water as ful. But am afraid if water will not be so scarce to the extent we have to que to get it.

I really prefer having water as a source of fuel but it isn't available right now so I would choose using LNG or liquid natural gas. But I think it's quite expensive because it involves a lot of works before it turns up to LNG. But I think most alternative fuels came from an intensive research. I've just hearn about ethanol and it seems that they are performing some research also. High school students even discovered ethanol on a plant, i've just forgot the name of the plant.

I always go for the cheapest one. So right now we just buy gasoline for our car.
