Do not pet the moose. You do not share a deep spiritual connection with them. They won't recognize you as a kindred spirit. They aren't your bestest friend in the world. Some of them may be quite cute, but forget about taking them home with you. It isn't going to end well for either of you.
Even not counting car collisions, a moose is more likely to injure you than a bear or a wolf. People fail to appreciate that even a small moose can weigh 800 pounds, and can kick hard enough to break bones. It's not uncommon for wolf biologists to find that wolves in our area have had their skull fractured seriously at some point because a moose kicked them in the head. And a wolf skull is a lot more robust than a human's skull.
And besides, you probably wouldn't like it if a total stranger (and a different species to boot) came up and started petting you, either. Even moose like their personal space.
Petting a moose is about as dumb as it gets.
