At least for calling a business, how about a law which requires companies who use automated phone services to send you to an actual person when pressing 0. Standardize the number to press and make it a requirement during business hours. It sucks getting trapped in an automated phone answering service when you 100% know that it can’t help you, only a customer service representative is able to deal with your situation.
I also noticed the reduction in operating temperature, which can help improve energy generation efficiency. Hotter panels produce less energy (generally speaking).
