Lowest Possible Benchmark

I think the reduction in speed on the Melbourne roads has resulted in a reduction in the ability of the drivers. It has effectively lowered the benchmark, so now the standard is down to the incompetent drivers who always drove at pensioner speeds. It has given every lousy driver permission to drive in their incompetent ways, unhindered. It has given every idiot permission to drive at 40 kilometres an hour, no matter what the actual speed limit is.
