I just did a google on this pr@@k and once you wade through the recent news, there's a few pages who mention an ex-cop SA lawyer Eugene McGee, who wrote an article "the need for speed" in regards to Police speeding while on duty.
Could this be the same one ? So he'd know the road rules pretty well...
Q: does he know how long it takes to get you BAC down below 0.05%, maybe 6 hours or so...
