Why does a car manufacturer have to care about theft at all?
This argument doesn't make any sense to me. Why bother with keys and locks then? Is it more practical to expect society to eliminate literally all crime?
I'm sure there are good reasons to dislike this lawsuit, but this isn't one of them.
If someone makes a dangerous product, it is reasonable to expect them to include appropriate safety features to reduce the risk their product poses to society.
The "victims" here aren't the automobile manufacturers, they're the people whose cars got stolen and those who were run over by a reckless joyrider or shot in a drive-by enabled by criminals having easy access to insecure, easy-to-steal vehicles. These are all people who wouldn't have befallen harm if these vehicles had standard anti-theft features.
The reason nobody's talking about suing bike manufacturers is because nobody was stealing bikes and riding around shooting people or crashing through the sides of buildings.
I think there is absolutely a legal argument that anti-theft features are critical safety features in cars, specifically. Not sure whether that argument will hold up in court, but it's not anywhere near as straightforward as "bike manufacturers don't have to care about theft, why should car manufacturers?"
