I agree.
New Zealand has a 12-hour limit, but you can go from one end of the country to the other in 12 hours. Did they put it at the maximum so that you're not going to drive a couple of times around the island before you get there? I think you're going to look at what you're going to put in place depending on your geography.
We don't know the reasons why they are there. What we do know is that they're inconsistent from one country to another, so there has to be something other than science that's driving them to have that basis. We are fully supportive of the science aspect in doing research and in continuous improvement. The better you know, the better you do. I don't think radical change is necessary.
