Hough lines/RANSAC are definitely on the same level of ad-hoc sophistication as Canny edges (in fact, Canny edges are often done as a preprocessing step for the voting scheme used by the candidate Hough lines).
Take a look at Figure 12 for an exemplary look at its failure cases -- cases that are much less forgiving than the aforementioned Palo Alto stretch 101 lane markings.
