I actually think he's said that emission laws are quite clear in the US, but that Europe is where they're unclear. From the Q1 call held on 4/26/16:
I think it is clear that we understand the U.S. environment relatively well, now having lived through for a number of quarters, through the type of expectations and having achieved, I think, a meeting of the minds with the administrator and then staff and it's about what is expected going forward. And I think we're beginning to tool ourselves and tool the organization to deal with that environment and adequately answer any safety concerns that a regulator of the marketplace might have.
On the European side, I had a chance to go through the report that was issued last Friday by the Commission that was presented by the Ministry of Transport in Germany. It is available now in English for anybody who's interested in it. I think it makes for a very interesting reading. I cannot disagree with the Minister, because I think he has pointed out, there is a result of the work that was carried out by the Commission, by the KBA and the Ministry itself. Given the way, in which European rules are set up and the way in which homologation authority is subject to devolution under the European arrangement that it is – there needs to be much better coordination across the national bodies about what it is that has effectively allowed as relevant technology in order to meet an emission standard.
