NHTSA investigates comma.ai’s openpilot over 5 crashes that killed 3

This one is outside what Retrofit Relay covers. The site focuses on home energy upgrades, weatherization, heat pumps, and rebate programs — not vehicle safety regulation or driver-assistance software.

The story here concerns a federal investigation into an aftermarket driving-assistance device installed in cars, not anything related to home energy efficiency, insulation, heating and cooling systems, or utility rebates. There is no connection to ACH50 air-leakage testing, HEAR incentives, heat pump installations, or any other topic a homeowner planning upgrades to their house would need to know about.

If you're looking for news on energy-efficiency upgrades for your home, this article won't have anything relevant. It might be worth checking whether a different summary was intended for this slot, since the content describes a National Highway Traffic Safety Administration probe into crashes involving a car software product, which sits well outside the residential energy space this site serves.
