LOL!
I could have used one on the Chicago, LA and Philadelphia freeways/toll roads, but I would hope to look far enough ahead to miss the overpass/overbridge.
It would have caused a multi-car pile-up over Cajon Pass, into LA with not a lot of trouble, but if one is on the 405 in LA, it might cause a lot of UFO sightings, desires to reach Nirvana, and traffic jams in Topanga Canyon.
Ejecting over Certain states could be risky...’Oh Skeet!’
