3.3 Initial speed analysis

As described in the main text, we performed the initial travel speed (0-0.4s) for the results in Fig. 3. 50 independent simulations were carried out in different mazes with different initial conditions. In free space, the initial speed can be estimated to be \(\langle v_{T, f} \rangle = \frac{1}{\pi}v_{max}\) as in the main text. Fig. S3A shows a good agreement between theoretical predicted mean speed and average speed from simulation experiments.
