Bert is a model S owner who has a commute to work that consumes 40% of his range. He has 50 amp charging at home and a supercharger conveniently located to his office. On a typical day, it is possible for him to charge to 90% at home and make it home at exactly 10%. Some days he needs to run errands immediately upon his return and he does not have time to charge his car at home and still make it to his destination on time. Which of the following scenarios do you think are abusive and which do you think are acceptable usage of the supercharger. Feel free to explain your position.

A> Bert charges every morning to 90% and only supercharges at work on days he knows for certain he will need to run errands when he gets home. This sometimes leaves him in a bind because these errands sometimes crop up at the last minute.

B> Bert charges every morning to 90% and adds 10% to 60% charge every day at lunch so that he can always be prepared if he needs to run any errands at home.

C> Bert charges every morning to 90% and also supercharges to 90% every day on his lunch break.

D> Bert carges to 90% at the supercharger every day on his lunch break and on the days he has errands he charges the minimum needed to make it to the supercharger the next day.
