> Wait for a smoking gun event like a car driving itself into a gathering of schoolchildren to get things started.

The actual gun industry has somehow managed to avoid being sunk by this problem by keeping the blame on humans despite a school shooting every few months in the US.

Cars will be explicitly advertised that you can turn the automation on, go to sleep, and arrive at the destination, but if the automation hits anything the sleeping human will remain liable. The misleading advert will not.
