I don't know, it sounds like OP was driving normally but thought they had missed something and would hit someone as their wife had screamed out of the blue, so dangerously.

I think you've read the situation wrong - the wife was playing Pokémon Go on her phone whilst OP was driving and because she was about to miss the Pokémon, she yelled stop and her partner (the OP) obviously thought that there was a real-life incident about to occur when she yelled stop and so they slammed on the brakes, causing the accident to happen. All I can say is that OP's wife obviously has a problem with addiction and should probably get help because she nearly killed them both.

Do blame Pokemon go and the idiots who play it.

That's right. It's a stupid game for brain dead, consumerist, zombies. Any person that plays it and are above the age of 13 are cunts.

The OP wasn't the one playing Pokémon Go, his wife was.

Funny because “Go” is a term for movement or starting up, not walking. So technically Pokémon Go can very well mean driving at the same time. However OP wasn’t play with the game and if he was, there is warnings all over the game

Yeah. I was thinking the same, or that the other car was running a light. The only possible thing that could make sense is if OP had a stop sign, and went to cross when he had just enough time to make it before the other car, but in that situation, they'd be highly aware of the other car(s) coming. Given that he's saying she yelled to stop to catch a Pokemon, if he had been at a stop sign, she could have gotten it easily, so the only reason to yell about stopping would require OP to be going at a decent speed. Therefore, someone was running a light to make this plausible.

Maybe the light just changed as he went through, but obviously the light wouldn't have accounted for someone braking suddenly at an intersection - either that or the other car was running a red light. Nevertheless, still a dangerous place to stop and I completely blame the wife.

Running a red light, in a parking lot, crossing lanes of traffic, driving straight across a busy road...wtf does it matter if you can reconstruct the accident in your head?

Because several FMLs turn out to be BS.
