Well, a popular way to commit suicide is carbon dioxide poisoning from running a gas powered car in a closed garage (see the movie Office Space). That won't work with a car that is entirely electric.
LAST NIGHT I DECIDED TO END THE PAIN. I PULLED THE CAR INTO THE GARAGE, SHUT THE DOOR AND JUST LET IT RUN. AFTER ABOUT AN HOUR I WAS REALLY SORRY THAT I BOUGHT A TESLA.
