> the european system does pedestrian and safety for other cars. I had no idea this difference existed. That's really interesting!

  before briefly working at a car maker, I was completely oblivious too. But there we had those crazy discutions about hitting pedestrians without breaking their legs, and designing the hood to receive them with less injury, and bumper height that would be more or less the same for many cars. here is an extract from a euroncap test (Volvo S90->pedestrian->Comments): "The S90 has an 'active' bonnet. Sensors in the bumper detect when a pedestrian has been hit and actuators raise the bonnet to provide greater clearance to rigid structures in the engine bay. Volvo showed that the system deployed for a variety of pedestrian statures and over a broad range of speeds. Accordingly, the system was tested with the bonnet in the raised (deployed) position. Protection against head injury was almost entirely good. The protection provided by the bumper to pedestrians' legs was good for all test locations and maximum points were scored. However, protection of the pelvis was poor at nearly all test locations."
