Yes, so my plan was to find "a soft place to crash" (lol) because I didn't have much time to think about anything else, we had already blasted through one red light and were barreling right towards another that had cars waiting. I was standing on the brake with both my feet at that point. It was pointless and the feedback I was getting from the pedal was rapidly diminishing, which I learned later was because the brake fluid was draining out.
Fortunately my passenger grew up driving beater cars that failed him regularly, he'd done this before so he reminded me the hand brake exists. Duh! Used the hand brake to gently* guide the car into the nearest parking lot and called for a tow. My thoughts went from "how do I kill the smallest number of people in the next 5 seconds" to "well I hope this shoe store doesn't get too mad at me for taking one of their three parking spots

" in what was probably the most dramatic tone shift of my entire life.
* When I tell this story I always make sure to say that it's vitally important to remember not to pull up on the brake too fast or you'll die. So I'm adding that here in case any younger people with less driving experience are reading. The hand brake/parking brake is a force multiplier. It is significantly stronger than the brakes you control with the pedal. Don't pull up on the brake hard. The force this will generate is equivalent to slamming your car headlong into a wall. The faster you are going, the harder you will stop. The anti-lock braking system will not work and it will not save you. Exert a calmness you may not feel and use small, slow, gentle pumps to slow the car and you will be safe. Practice in an empty parking lot while driving slow slow slow. Don't be like me and do it for the first time when your brakes fail.
