We here at AirFlow Deflector support the Stop Underride Act which calls for energy absorbing underride guards for protection at real-world speeds which are around 40-50 mph here in the U.S. Side underrides are a different situation here in the U.S., we have zero required side underride protection. These crashes often can include lane changing glancing collisions that even a low-speed guard could provide good protection for. They of course work for bikes, motorcycles, and pedestrians.
