<p>Variables of bimodal Gaussian fits (μ1, μ2, σ1, σ2, and p) from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0125461#pone.0125461.g003" target="_blank">Fig 3</a> were interpolated (using cubic spline interpolation) across noise levels. This demonstrates an estimate of the probability of where on the road a subject will be at any given instant as a function of motor noise.</p
