We could do with speed limits like that in Australia. In Victoria we have 40km near schools and busy shopping areas, 50km in heavy suburban, 60km in light suburban, 100km on local motorways and 110km on interstate motorways. There are also various 70km, 80km and 90km areas, supposedly for safety, but equally likely as reveune earners near fixed speed-cameras. Having written this I now realise that the growth industry in Australia is road speed signs
