For motorbikes I think the position has settled that it's seen as contributory so any payout might be halved (i.e. if you're hit filtering past the outside of stationary traffic the car that pulls out etc is not fully to blame and you should be ready to stop at any time). But that doesn't say that blame can't be apportioned differently when one party is doing a dangerous and unlawful act as here... and in any case, having lower damages isn't the same as no case to answer.
