Hologram for safer motoring

Travelling by car on long trips may bring one into areas where the culture is much different than one's own. To better fit in and reduce paranoia some people place hats on the package shelf inside the back window of their sedan in the hope these will show them to be smypahtetic to the locals. Bearing logos and coloration such as sports teams, college or professional, or organizations like NASCAR or Police charities the hope is to not get a traffic ticket or have one's car turned over by a violent mob, etc. The propsed invention is a hologram projector linked to data that would be used to project the properly logoed and colored hat onto the package shelf and protect the occupents from above mentioned mayhem. This system would be auto or manual depending on chosen options. Auto mode would be GPS triggered when crossing into unfriendly territory such as certain geopolitical hot spots or other slums.
