Here in Cape Town, South Africa, Lane splitting is the norm, and legal.
The only way to travel during peak traffic, and the main reason why I got two wheels.
The taxis(10 seater mini-buses) are notoriously bad drivers, ignoring traffic signals, and driving on the yellow line.
However that independent spirit also translates into them having a soft spot for bikers, because they always make space for bikers to squeeze through during the peak traffic hours just mentioned.
Some drivers do just swap lanes without signaling.
The trick is to only be slightly faster than the cars, so there is plenty of time to react.
That, and watching front wheels, and trajectory, and adjacent spaces.... Then you can be assured of arriving safety.
