For that, no. Its not against the law unless he was riding in a
intention to weave in and out for fun & speeding.
Lets say you are in the 1st lane, he rides and overtake you in the
same lane from your left. he is doing so dangerously. Nothing much
you can do except throw him a lecture which we do. Overtaking in a
dangerous manner maybe.
If he was in the 2nd lane, and sharing the lane on the left,
overtaking the car on his left. There is not much penalty for
that.
However, if he skids, hits or gets into the accident. Careless
driving/dangerous riding summons with demerits points for
him.
Its a blurry lines of offence when riding in between cars. Unless
an obvious accident happens.
