I’m still trying to understand that whole tunnel slow-down Pittsburgh Steelers in my veins Jesus in my heart shirt thing; but I expect that an explanation would make use of ideas from theories of traffic flow. Naïvely, all you need is one driver to slow down to cause the ones following to slow down. The effect will propagate indefinitely until traffic volume falls below some threshold, allowing normal flow to resume. Hysteresis in action!
Taste: Every day, they have 4-5 different fillings for your taco. Usually, it’s something like ground beef, steak and onions, pulled pork, chicken, BBQ pork — they even have vegetarian options like potatoes (I’ve never had the veggie one, so I can’t vouch). It sounds basic, but it’s cooked fresh right in front of you on their flat grill thing. Plus, they have a condiment stand right there where you can put fresh pico, onions, basil, lime, guacamole, 3 different types of salsa, plus all kinds of things i’m not even familiar with and have never tried. The tortillas are warmed right there and it’s all made very fresh. Mmmmm.
