While using ford Blue cruise I have found a major major safety flaw. While using blue cruise hands free driving over a major bridge in the middle of the day the car swerved a very hard left. Almost forcing me off the bridge. I believe the shadows that were cast on the bridge made the cars system malfunction. The incident has happened twice now and also someone else who has the same car in another state on a similar style brige with similar shadows while using blue cruise said the same thing has happened to them.
