auto glass is tempered. as soon as you scratch it, it will probably shatter.
you can't do this; why would you want to?

DON'T DO IT!!!! Automotive windows are made of safety glass and as soon
as you drill into the surface, it will shatter into thousands of pieces.
I recently recall someone trying to cut into safety glass and it was a
mini explosion.
For something of this nature, I would suggest talking with a company that
deals with automotive windows as they may have some alternative ideas for
you.

and if it does'nt explode, it will eventually.

There are two kinds of glass in most American autos: tempered and
laminated. If you have or borrow Polaroid sunglasses, tempered glass will
show up (under a clear sunny sky) as having dark and light areas as the
stress in the glass changes the polarization of the daylight. Laminated
glass has a layer of plastic between two thinner sheets of glass. Under
US law, the windshield must be laminated to keep people from going through
it. Other windows may be either. My experience has been that sides are
usually tempered and back may or may not be laminated, but then I have
owned my cars an average of 7 years each which doesn't add up to many
cars. Laminated should be drillable, tempered is not and crumbles to
little pieces. Of course, laminated may crack when drilled or
delaminate if moisture gets in. Perhaps you should find another way to
get out back (glue it on and run any wires through the trunk.)
