[Maine❥Acadia National Park] The self-driving traffic here is a bit awkward. On a sunny day, the highway can only drive 20. When it rains heavily, it is better, and it can drive 40. However, the road is long and blocked, with many and deep potholes, and the road cannot be seen. I can't hold the steering wheel either. But when you get to the park, everything is great, very beautiful, and you can even have someone to play with.
