1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the computer to:
- identify an occupant of a first vehicle;
determine a time difference at which the first vehicle and a second vehicle would pass a predetermined point in a roadway;
predict a time to collision between the first vehicle and the second vehicle with a forward collision warning subsystem;
provide a first output in a wearable device of the occupant in the first vehicle when the time difference is less than a predetermined threshold, the first output and the threshold based on the identified occupant; and
then, after providing the first output, provide a second output in the first vehicle when the predicted time to collision is less than a second predetermined threshold.

Abstract
A headway between a first vehicle and a second vehicle is determined. A predicted time to collision between the first vehicle and the second vehicle is determined. A first mechanism in a wearable device in the first vehicle is actuated when the headway is less than a predetermined threshold. A second mechanism in the first vehicle is actuated when the predicted time to collision is less than a second predetermined threshold.
