After the filtering of our concepts through the concept After the filtering of our concepts through the concept selection scoring process we have concluded that no selection scoring process we have concluded that no bumper would be the first choice. However it is believed bumper would be the first choice. However it is believed that the 360-degree bumper should be developed for that the 360-degree bumper should be developed for safety reasons.safety reasons.
