Well that's the issue, isn't it? There was no evidence that the previously expected regime meant poorly tested and uncertified (when the opposite is true, which is why such vehicles haven't already been flying here when they've been under testing in New Zealand for years), it was something that you kind of assumed. NIMBYism is also a reflexive siding with harder regulation as obviously necessary without good evidence, entrenching a flawed status quo which doesn't have to meet the same impossible standard.
