Figure (image) The Korea Advanced Institute of Science and Technology (KAIST) Share Print E-Mail Caption Drivers' competitive network and collisions. Nodes are drivers. Nodes encircled in black are labeled by name. Edges denote joint competition in at least one race. Red edges connecting nodes indicate that the two drivers collided at least once. Using Fruchterman-Reingold, nodes are generally proximate to the extent that their average structural equivalence (over all races, from 1970 to 2014) is high.
