Furthermore, something they alluded to but I would love to see the actual data on; when a car does a rolling stop at a stop sign, they are typically going just as fast as a bike that doesnt even slow down for one! It only feels slower because the car was going 60 km/h, and had to slow to 15 km/h to roll at the stop sign. Meanwhile a cyclist is biking at roughly 20 km/h and to slow to that same rolling speed would be almost imperceptible. So it seems like bikes are gliding through stop signs, and cars slowing down, when they are rolling through at the same speed.
Our human perceptions of speed are actually more tied to acceleration and deceleration.
