If we do this (and we should) we’ll need to undo a lot of substandard road works and additions. Plenty of roads built to design speeds that would support 130km/h or more and then modified in ways that drastically drop that speed.
Victoria’s approach to shoulders on highways and freeways springs to mind. Likewise the biker slicer tensioned wire fences. What they catch at 100km/h they’ll start to roll at higher speeds as they already will do with 4x4s and SUVs.
Yeah fairly common to see in the inner west now as well. People don’t have a tonne of choice but it’s not particularly safe, either electrically or for pedestrians who may not necessarily be able to navigate over the top of it all.
