The problem they were trying to solve is someone typing in “Woodbridge Lane” as the answer and then later typing “Wood Bridge” or “Woodbridge Ln” or “Woodbridge Ln.” when prompted.

This was the wrong solution.

Still rather unsafe, right? "Cambridge" would be closer to "Woodbridge" than "Woodbridge Lane".
