We actually already have a system in place now, since 2005. Right now we have a 48-hour rule for anything that leaves by a vessel. Going to 72 hours could certainly help, and I think no legitimate trader would argue against that.
Part of that process in the U.S. is not that they actually look at the vehicle or in a container. They look at a title. You submit a title to U.S. Customs 72 hours before a container can go onto the boat.
