Bloatect Ingestible Air Bags. Designed as an airbag alternative to reduce the injury from whiplash. Sure, they were prone to detonate at even the slightest jostle and there were 95% more cases of premature detonation than the airbags working as intended, and yes, ingesting multiple capsules could lead to popping; but you can't really put a price on the comfort and security of knowing that there's an airbag inside you that could go off at any moment.

Recalled because of a number of instances of teenage punks using ingestible air bag  capsules to derail trains.
