(Normally this is in the *opposite* direction as the pedestrian, but if pi is negative, it indicates that cars are swerving *towards* the pedestrian.) pi and tau are proportionality constants that depend on local road conditions, the time of day, the police officer's mood, and so forth, with the one constraint that 1 / sqrt (pi * tau) = the speed limit. --- End of Central America ---
