This was terrible, and the obligatory "fuck cars," but are they sure it was an intentional jihadist attack?
I remember this :

the guy claimed he mistook the gas for the brake, for 10 whole seconds of carnage and destruction. Got believed too, because old geezer. This one is a middle aged psychiatrist but a stroke or too much of his own medicine are just the first possible reasons I can imagine.
My red and green this Christmas is fat sweet cherry tomatoes ripening in the sun on my balcony. I would love a little rain to ease the fire danger in the hills, but I had all the snow I need for life during college. It's funny the snowy people who said they can't even fathom green, if it weren't white it would be brown, they're right about their reality but you asked for a dream. I'm living the dream.
The other nice thing about being in Los Angeles at Christmas is that it's quiet and there's very little traffic, because so many people rushed off to visit the snow, either local skiing or far away.
