When done sensibly, at low speeds, lane splitting is a reasonably safe practice but, sometimes motorcyclists are hard to see when coming up behind you between lanes, and if you decide to change lanes, there is a risk of a collision. To help mitigate that, there is a new patent filed by engineers from Ford that uses cameras and other sensors to help a vehicle detect lane-splitting motorcyclists and intervene where appropriate.

The system proposed by Ford would use rear-facing cameras to detect motorcyclists approaching from the rear in the inter-lane zone.
