Yes and no. We should be able to drive at 140 on the Mitchell Freeway without any problems. The outer lane is the fast lane, but is primarily an over-taking lane. So many people crawl along at 90 refusing to pull over. Admittedly there are roads in WA that are poor quality, but some are fine. I think the overal driving standard in Perth is pretty poor. I only came to that conclusion after doing a lot of travel and coming back to Perth.
