I'm ok driving the e-car to work if I know for sure I can stay there until well past 7pm. If there's any chance I might need to leave before 7pm I want to drive my other (not electric) car.
On the few days where I need to leave early and can't drive the gasoline car (because wife needs it), I spend all afternoon stressing about it and walking to the parking lot every 30 minutes to look for empty spots to get the charging started ASAP so I can get home. Not fun.
