Loved this idea.

Just dont know how to incorporate it?

Its not like I need a wine glass holder while I am driving, but to keep a glass from spilling around a 3 year old is a daunting task.

My son and I went to an "RV and Camping Show" at the local civic center.  Was not much of either, but there were a bunch of boats.  In one of them was this gem of an idea. 

The wine glass slides into and becomes secure from being knocked over.  Isn't that great?  No longer worrying about that old growth red Zinfandel becoming a part of the fabric!

It fits in standard cup holders.
