Helpy McHelperson

A person who goes out of their way to be helpful to you regardless of laws or expectations in such a way that though they are being kind, they are actually making a situation worse.

Examples of some situations:
 * You are stopped at a stop sign and a driver on a cross street without a stop sign stops for you anyways, waving you through the intersection without realizing that there might be other traffic approaching
 * You approach a street crossing on a trail and a driver stops to wave you through other lane(s) of traffic may not have stopped, a problem especially at Memorial Circle
 * You are in a Metro station, and someone offers to carry your bike down an escalator (this is not allowed and will probably get you yelled at; you're supposed to use an elevator or stairs)

Reference
A exaggerated and redundant way of making up a name to signify helpfulness, there is no word in English to describe this. However, there is a Japanese term Arigata-meiwaku which means the following:
 * An act someone does for you that you didn’t want to have them do and tried to avoid having them do, but they went ahead anyway, determined to do you a favor, and then things went wrong and caused you a lot of trouble, yet in the end social conventions required you to express gratitude
