G'day,
According to the Queensland 2003 Transport data which is the only data published, less than 4% of crashes involving a fatality or serious injury are CAUSED by exceeding the posted speed limit. This fact is supported by international research.
The Queensland government, and all Australian state governments use the line that "in 20,27,25,22,16 percent (insert appropriate percentage) of serious crashes, at least one vehicle was speeding. Speeding is defined as exceeding the posted speed limit or exceed the
speed appropriate for the conditions. However, even the police forensic crash investigators only claim their estimate of the pre crash envelope speed is accurate to 10% to 15%.
No government will (or can) tell you how much speed contributed to the crash or even how it contributed.
Write to your transport department or your transport minister with these questions and they conveniently ignore the question and any data presented. They reply with the standard bunch of lies.
Surprise, the government tells lies. Of course the speed excuse is most palatable to the masses who don't know how to drive and don't want to. It is a cheap and easy option.
Stuff 'em, they cannot make you retro fit these devices and they won't work id retrofitted, especially to by 35 yo car.
