Those would be very expensive trailers and the current shipping container ecosystem (and semi trailer ecosystem) could not cope with $100,000 unloaded trailers just sitting in unsecured areas like normal trailers do today. You're right that it would be convenient for the driver, but I don't think it would be convenient for anyone else. Actual trucking professionals please correct me if I'm wrong about any of that.
