For the record, I'm completely against any kind of enforced black box, even for speeders or the newly passed. Insist they have them, and it's a slippery slope until we all have one and fun hoons are essentially banned. That would be an incredibly dark day for motoring, mark my words.
Docwra has it right when he mentions that there is appalling driving standards in this country, and that is far more of an issue than the current speed limits with regards to non-flowing traffic as well as accidents. Until we sort this out by compulsory retests every few years, it'll never go away. Even now, I get close to feeling physically sick if I'm on a multi-lane road and there is a gap to my left I could pull into, so I do so.
Pull over I mean, not be sick I've no idea how MLMs can just sit there and not realise that they ARE the problem.
