A Cybertruck owner forum has a complaint that when a driver tried to touch climate control, the knee airbag deployed.

The fact that it was specifically the driver knee airbag deployed while the driver was interacting with driver climate controls… suggests the Tesla system lacks proper debouncing or validation logic to filter out false positives.

This is exactly the kind of systemic safety failure that strengthens the Piedmont crash lawsuit. Tesla’s defective approach to vehicle safety integration needs more exposure. I’m tempted to write up a detailed look at why. Here’s a quick back-of-napkin sketch.

• False crash signal generation: airbag control module may have received bogus deployment signals, possibly from electrical noise or a fault in the crash sensor network
• CAN bus cross-contamination: touching the climate control (which communicates via CAN) may have introduced signals that the airbag system misinterpreted as a deployment trigger
• Grounding or electrical isolation failure: low-voltage interface action affects a safety-critical system
• Software logic error in the airbag deployment algorithm
