There are HUGE holes in that assumption in the form of non-metallic 
parts and paint preventing contact between metal parts. An enclosure 
forms a Faraday cage ONLY if it is continuous. and ONLY if all 
conductors penetrating it have either a feed-through to the enclosure 
or, if a shielded conductor, the shield is bonded to the enclosure at 
the point of entry.

Modern vehicles have lots of paint between metal parts. When I used 
Hamsticks on my Volvo S80, I had to bond the mount to the trunk, and I 
had to bond around the trunk hinges.
