A non-wetting liquid is pressed between a rubber cap and a solid plate. When the plate slides at a velocity U larger than a critical value , the contact is lubricated. However, if the sliding surface carries a nucleating centre (a local depression), a “dry wake” can be induced, with a well-defined wake angle , as in Čerenkov radiation. We interpret this by a competition between a dewetting velocity and an invasion velocity U. The Mach relation is obeyed. These effects are relevant to the hydroplaning of cars on wet roads.
