The nets — placed 20 feet (6 meters) down from the bridge’s deck — are not visible from cars crossing the bridge. But pedestrians standing by the rails can see them. They were built with marine-grade stainless steel that can withstand the harsh environment that includes salt water, fog and strong winds
20 foot drop onto "nets" made of stainless steel? I feel like this may still be a fatal fall.
Edit: I'm not negative on the idea, but it sounds like you are still having a pretty bad time if one of these nets saves your life.
