## Comment Car analogy (Score 3, Interesting) 145

It is the same as selling a car saying it has a 20 gallon gas capacity, then finding out that the tank itself is 15 gallons and there are 5 one gallon gas cans in the trunk. Yes, there's 20 gallons. Yes, it is all usable. However using the last 5 gallons is slow because you have to stop the car and keep adding it to the tank.
Sure, you're getting 20 gallons, but it can't all be used at the same time.
