Relative Rain Vector (Scope Key)
$$\vec{v}_{\text{rel}} = \textcolor{#0ea5e9}{\vec{v}_{\text{rain}}} - \textcolor{#10b981}{\vec{v}_{\text{car}}}$$
Surface Wetting Rate (Flux $\Phi$)
$$\Phi = \max\!\big(0,\ -\vec{v}_{\text{rel}} \cdot \hat{n}_{\text{glass}}\big)$$
Where $\hat{n}$ is the normal vector of the glass plane. Only drops moving into the glass ($\Phi > 0$) accumulate.
