The items I carry take up less space than half a dozen eggs. Yet I have things that clearly the average person just doesn't carry in their car. That, to me, would be more convincing to a police officer or some other suspicious person than, say, a toolbox (which lots of people carry, even thieves). Another thing I carry in my glove compartment is a map of the city showing the different brush pickup zones and dates (from the city website). That, too, is something the average person would never have with them.
