The manual for the same companies skiing airbag points out that if the GPS drops out, the airbag is disabled. [0] That should pretty clearly indicate how well they take safety.

- shakna 6y agoHow can any designer of a safety product justify it having any kind of software shutoff? Safety products must _failsafe_, especially in unexpected situations. This is just failing hard.

- shakna 6y agoGPS has service interruptions. Planned and otherwise. GPS jammers may be illegal, but they exist, which means that they can be encountered. Wet leaves on trees have been known to degrade GPS signals. Cross-country skiing exists, and may proceed through forests that are... Wet. GPS connectivity can be impacted when switching from one satellite to another. Safety equipment _must_ have a _failsafe_, not depend on the assumptions of the software. At no point in time is it reasonable for it to depend on something external to itself for whether it works or not.
