I love the idea...I could just see people asking "WTF is that???" I've never liked a T-shirt idea before this one.

Just don't use foggy headlights in the silhouette....and, as Mikey said, the text on the back needs serious help. Looks like Times New Roman -- we can do better than that!! And no I don't know how to change it!!! Perhaps a simple CEG logo on the back would suffice.
