I've experienced this outside of protests. My wife and I were driving somewhere near downtown St. Louis, on a part of the interstate where there are tall concrete barriers between the directions of traffic. There was a complete log jam due to an accident ahead, and we heard sirens coming up from behind us to the left. We were in the left of two lanes. The right shoulder was either filled up or too small (can't remember), so people couldn't really pull right more than a foot or two to allow the ambulance through. The ambulance didn't let that deter them. They took the foot or two we and the other left-lane drivers could give by getting REALLY close to the car to our right, and used it to careen down the left shoulder, scraping the side of their vehicle along the concrete barrier much of the way.
