I propose that we change the definition of intersection to the one that is in the current (2009) version of the MUTCD (Manual on Uniform Traffic Control Devices):

Intersection—intersection is defined as follows:
(a) The area embraced within the prolongation or connection of the lateral curb lines, or if none,
 the lateral boundary lines of the roadways of two highways that join one another at, or
 approximately at, right angles, or the area within which vehicles traveling on different
 highways that join at any other angle might come into conflict.
(b) The junction of an alley or driveway with a roadway or highway shall not constitute an
 intersection, unless the roadway or highway at said junction is controlled by a traffic control
(c) If a highway includes two roadways that are 30 feet or more apart (see definition of Median),
 then every crossing of each roadway of such divided highway by an intersecting highway
 shall be a separate intersection.
(d) If both intersecting highways include two roadways that are 30 feet or more apart, then
 every crossing of any two roadways of such highways shall be a separate intersection.
(e) At a location controlled by a traffic control signal, regardless of the distance between the
 separate intersections as defined in (c) and (d) above:
(1) If a stop line, yield line, or crosswalk has not been designated on the roadway (within the
 median) between the separate intersections, the two intersections and the roadway
 (median) between them shall be considered as one intersection;
(2) Where a stop line, yield line, or crosswalk is designated on the roadway on the intersection
 approach, the area within the crosswalk and/or beyond the designated stop line or yield
 line shall be part of the intersection; and
(3) Where a crosswalk is designated on a roadway on the departure from the intersection, 
 the intersection shall include the area extending to the far side of such crosswalk.
