1. A system, comprising a computer including a processor and a memory, the memory including instructions executable by the processor to:
predict a collision time between a corner point of a host vehicle and a target vehicle, the collision time being a predicted time at which the corner point of the host vehicle attains a same position as the target vehicle;
predict a relative heading angle between the host vehicle and the target vehicle based on the collision time;
predict a reach time for the corner point of the host vehicle based on the predicted relative heading angle, the reach time being a predicted time at which the corner point of the host vehicle reaches a longitudinal distance threshold;
determine a threat number based on the lower of the collision time and the reach time; and
actuate a vehicle component based on the threat number.
