if the glass fails Musk doesn't get sued, he replaces it under consumer protection laws.
As the manufacturer of the vehicle he is in the gun first and foremost. He can then sue the glass manufacturer to recover his costs.
"Sometimes an action may be taken against the manufacturer instead of, or as well as against the supplier. For example, the contract might not give the injured person the necessary legal rights or the manufacturer may be better able to meet large claims because it is adequately insured. There are statutory rights against manufacturers under the Australian Consumer Law, which is contained in schedule 2 of the Competition and Consumer Act 2010 (Cth).
Manufacturers are usually sued for breach of the guarantees contained in the Australian Consumer Law [see in particular schedule 2, ss 54-56], for breach of other provisions of the Australian Consumer Law [see in particular shcedule 2, ss 106 and 138] or for negligence at common law.
The extent to which negligence, or carelessness, must be proved varies from case to case. It commonly involves satisfying the court that it was more probable than not that the plaintiff's injury was caused by the negligence of the manufacturer"
