1. An apparatus for vehicle control, the apparatus comprising:
a processor configured to:
receive, while a driver is operating the vehicle to traverse a vehicle transportation network, vehicle operation information including at least a current speed of the vehicle;
retrieve, from a planned path of an in-vehicle navigation system, an upcoming turn in a current road when the driver is using the in-vehicle navigation system, wherein the upcoming turn in the current road comprises data regarding a curve in the current road that causes the vehicle to advance along a new road different from the current road;
retrieve, from map data, the upcoming turn in the current road when the driver is not using the in-vehicle navigation system;
determine whether, during the upcoming turn, wheels of the vehicle will maintain contact with a road surface at the current speed; and
issue a braking instruction to a control system of the vehicle responsive to whether the wheels of the vehicle will maintain contact with the road surface at the current speed.
