I think the tow bar debacle and certification that Simon Court from the ACT Party mentioned before, that was a big issue just a while ago when all of the tow bars on trailers that were, in the Ministry of Transport's view, not adequately certified. And that caused a lot of chaos. Now, we have to really get that right, and that's going right back to the beginning and making sure the people that are doing the welding, doing the designing, are adequately trained and adequately certified. But a lot of these tow bars had been in service for quite some time. So if they were dangerous, they weren't just dangerous on the day they decided to go and review all of this and pull all those trucks and trailers off the road, they'd been unsafe for years, in some cases. So we owe it, in the name of safety, to get these things right, right from the beginning instead of leaving it way until after the fact when it could've actually caused quite serious issues. Same thing with buses and bus designs, as the member mentioned earlier.
