It says the bus has a top speed of 60km/h..which during peak hour is still faster than traffic generally flows on the freeways, and is at least a constant speed PLUS it can carry quite a few (1200+) passengers at any one time.

I'm sure people will get used to the sensation of having it pass over them, Perth drivers are usually too focused on their speedo to notice anything else that goes on immediately around them let alone over them.
