It's an open invitation to theft.
Thieves know all the obvious places to look.
Do not leave luggage, packages, or other easily removed items in view inside your automobile. Lock your property in the trunk. Doctors should always conceal their bags while away from their vehicles. Automobile thieves frequent streets and parking areas in the vicinities of public gatherings. Do not take needless risks by leaving valuables in your car when it is not necessary to be transporting them.
