I first saw this on another website and couldn't find it here. I even put down "Jaywalking" to look for in games and got nothing! It's nice that I managed to play this really cool game. I think the best part about it is how you can experiment so well with it. I'm pretty bad at it actually. I managed to get 8 out of 25.
Here's the thing I used to get across. First, go to the end of the first streets where the cars are coming from the opposite side. It will give you that much more time to see what's coming at you. I imagine most people have already figured this out.
