Please Explain Lane Splitting

I wonder how a motorcycist would like it if a car lane split? Lol

Around here? Saw it the other day. Bike was making a left turn, car was going straight. All waiting for the light. When the car pulled up next to him, the guy flipped up his visor and started screaming ****.

On the other hand, I seen guys on road bikes not give a ****. Just depends on the personality of the rider.
