I think pushing someone into a barrier is always going to end badly, it didn't help in this case that they seemed to come unlinked and flew in to the rest of the riders but even if it was a solid wall the rider being pushed could easily cause a pile up after impact.
So yes some of the set up could have been better but the only thing that would have stopped this situation being as bad as it was is if they sprinted in a straight line.
Sure if the barrier is solid. I’ve never had the sense that they are designed in anyway to improve crash outcomes above simple separation from the crowd. Indeed the feet to these barriers often cause crashes. Seems fairly negligent.
