Flexibility and durability. You should always find the wiring in your vehicle with multi-strand cores. Solid core wires break a lot when placed in physically stressing environment, like a vehicle where the frame is vibrating a lot and subjected to a bunch of stretching aand warping as the vehicle shifts during turns, acceleration, and braking. Most applications that have a lot of vibrations will use multi-strand core wires as well.

Homes tend to have solid core wiring since they are generally stable and don’t move much.
