The average thief is a lot smarter, stronger and good with tools than you think.

They also network and know a lot of stuff.

They know that people rarely put anything more valuable than a few coins in glove boxes and so rarely bother opening them.

[bamboozled]

Seen a lot of cars that have been broken into, seen a lot of open glove boxes too.

[bluGill]

rare is not never, so if the effort is low enough some will open them and search quickly.
