Five cars on a one-lane road. No passing allowed. How many groups arrive at the finish line? Watch the simulation — then guess.
Use the scrubber to step through the simulation. Cars in front block cars behind them — faster cars get stuck.
Five cars. Position, speed, target = 12. No passing allowed. Step forward to watch the road resolve.
The car at position 8 (speed 4) is gaining on the car at position 10 (speed 2). They reach the same point before the target. What happens?
