Yeah except the tones and walk messages still play, it just doesn't spam wait over and over at a red. Do you think because it's playing a satirical message blind people will ignore the tones and just start running into traffic?
Why does it spam wait over and over? Have you considered that there's a reason?
I don't think it even does spam "wait" over and over; I've never heard that in my life. With every such crosswalk I've encountered (in multiple cities across the US) it only says "wait" for each time you press the button.
Seems like: yes because the hacked message could say "cross quick right now".
