Well people don't top of their gas tanks every night before they go to bed, they only refuel it when needed........

Which is like every few days or weeks depending on how much a car is driven. Unlike a electric car which is practically empty after every drive........

When the 918 comes home, it doesn't always get the same parking spot where the charger is located, not a problem, it doesn't need to be charged every night, it has a gas engine to recharge the battery if needed.

There are all sorts of reasons why people can't plug in their electric car at night every night, the charging spot at the apartment complex is taken up, they spent the night parked on the street outside of their girlfriend/boyfriend's home, friend's home, etc. 

Here is one typical scenario, someone drove the Tesla all day, be it for work or whatever, he planned to go home and plug it in, but a booty call comes and he spent the night at the girl's place, the Tesla is practically empty the next morning and can't last the drive back to the office or home where the charger is located.
