This type of attitude concerns me. A person with this type of controlling and obsessive behaviour is not unlike that of a stalker. The inability to either confront the individual in a polite friendly way and instead internalize the perceived "conflict" as intentional harassment is cause for concern as it could escalate.
But in answer to your questions - yes, a POLITE and reasonable request to the FCPS transportation department could lead to a slight re-staging of the pick-up location. I know first hand of people who have had some problems with a particular bus stop and have had it relocated. Not far - perhaps just to the other side of an intersection. But you have to be nice and have a reasonable explanation for why you request this change.
