I once crashed into the back of a car at a stoplight and bent my fork, which pushed my fender struts right up against the downtube and prevented the front wheel from turning more than a few mm in either direction. Without knowing this, I picked myself up off the trunk, then tried to ride across the intersection to where the car had pulled over so I could apologize to the driver. Damn near ate pavement in the middle of the road.
