That's a Bedelia cyclecar ambulance prototype. During WWI, the French army thought cyclecars would be a handy way of getting injured troops off the front line and to bigger, conventional ambulances that couldn't maneuver in the cratered battlefields. They were wrong. The bicycle tired cars got stuck in the mud and even the lightly injured would be critical by the time they got to a medic. Makes for some hilarious old photos, though. It's like they're bringing home trophies after an afternoon of The Most Dangerous Game.
Bedelias had a really fun seating configuration. Gives new meaning to the term "backseat driver," amirite, fellas?
