Whilst I was heading north on Reefton Spur last weekend, I witnessed a 4WD with Govt. plates (unmarked police?), driving quite recklessly, "excessive" speed* and crossing unbroken centreline through blind corners, on some occasions being entirely within opposite lane... a sure potential for head-on collision with a motorcycle! Anyway, I had the camera running, and would've captured their plates, but the video file got corrupted somehow and wont playback, even after attempts at repairing the file. I'd make more of a recovery effort, if I thought that authorities would actually do anything with said evidence. Seems all I can really do is vent to anyone who'll listen! * Might well have been within legally posted limit, but the only way they could corner at that speed was by taking a "racing" line, thus frequently entering opposite lane.
