This probably doesn't qualify as a true hidden Mickey, but it's a fun one to consider. This Mickey was formed on my car's GPS screen as we drove I-5 in Anaheim on the way to Disneyland. The three circles are formed by the icon for my car and the two offramp circles. The 5 freeway runs all the way up California, but this formation can ONLY be seen on the 5 freeway at Harbor Blvd - the exact exit for Disneyland.
