A guy bought a BYD electric car 18 months ago. It was the biggest purchase of his life. He drives it to the office. He plugs it in at night. He drives it again. That's the entire relationship. He treats it exactly like his old petrol car, except quieter and without fuel stations. He loves it. But he's been quietly frustrated for a year. The range is never what the brochure said. The cabin is boiling when he leaves the office at 5 PM. The brakes feel strange, and he's never sure how hard to press. Every power cut at home leaves his family in the dark. And he's never opened most of the menus on the big screen. Then a friend who services electric cars at a dealership took a ride with him. He's been an EV technician for 6 years. He watched him drive for 10 minutes, looked at the energy screen and said 8 words that made him pull over: "Your car is a giant battery. Use it." He thought it was a joke. It wasn't. By the end of the weekend, he had changed 11 things. And the next time the power went out, the lights stayed on. Here's everything his friend showed him, in the exact order. 🧵
