The individual value plot shows all of the observations. Each row of points represents the data from one of the groups formed by the factor levels.  

For the driving data, the first row of points shows the response (number of driving corrections) for each of the inexperience drivers (Experience = 0) on the first class roads (RoadType = 1). The plot suggests the number of corrections may differ between groups. However, the variability seems similar within each group. This is consistent with the high p-value for the multiple comparisons test.
