City of Perth considering 40km/h speed limits

City of Perth considering 40km/h speed limits. Why don't we just get out and walk ? https://www.perthnow.com.au/local-news/perthnow-central/city-of-perth-consider-expanding-40kmh-speed-zones-throughout-the-city--c-18080000

EDIT : Alot of you are replying "it's already like that in the city" or "40km/h" is enough for the city. The point of the article is that they want to broaden this beyond the city. From the article

"The City of Perth is considering expanding its 40km/h speed zones to all its local roads in an effort to improve road safety, accessibility and encourage more pedestrian friendly streets"

That's why i posted this.
