The issue is not that there is a wait at all, but the length of the wait.

While 60-80 secs is not a long time, human behaviour is conditioned by expectation. Most pedestrian controlled crossings have a shorter minimum wait. One you've waited longer than you are used to, the subconscious starts kicking in, questioning if the lights are working properly, making you impatient. It's not a conscious thing, it's conditioning.

I was in Spain recently and saw pedestrian crossings that gave you the countdown until you'd get a crossing light, rather than what we commonly have here, which is a countdown for how long you have to cross. The former might be helpful. Or it might make people think: 60 seconds? I'm not waiting that long.

Separate entirely from this is the foolishness of trying to cross through standing traffic towards a lane where traffic is moving freely and can't see you, when there is a safe crossing provided. That's a bad decision, pure and simple. I don't suppose any of us are innocent of making bad decisions, so let's not judge.
