Hands OFF the wheel — the Buick drove itself 🙌😳

Training day at Monticello for Leading the Charge 🏁 GM put us in the new Buick Enclave with Super Cruise — and the car did the driving. Hands off the wheel, eyes on the road, and it handled the whole stretch by itself.
This isn’t the future anymore. It’s on the lot.
Would YOU trust a car to drive you hands-free? 👇

POV: your salesman trains on electric trucks in the mud 🛻⚡
Caption:
Not a normal Monday 😎 Out here at Leading the Charge — GMC and Buick’s EV training — putting electric Sierras through the mud so I know exactly what these trucks can do.
Your salesman shouldn’t just read the brochure. He should’ve driven it.
Would YOU take an electric truck off-road? ⚡👇
