While driving east bound on Hwy 24, once I crossed the Caldecott Tunnel, I saw what I am pretty sure was the new GX550 in Green color on the side of the road. It seemed the vehicle was not stalled on the freeway but it was driving in the slow lane and headed for an exit. It was too bad I could not pick up my phone in time to take a picture. Has anyone else noticed this vehicle on the road in the Bay Area?
