Man! Read the old stuff! He had friends and he talked to civilans in 39. He even asked for the goddamn way once! In a very friendly and polite way!
He clearly had friends in the 1989 movie, at least as much as he ever did in the comics. You know, from that giant party? Just because the movie didn't spend time ON his friends doesn't mean he didn't have them. As for the rest, welcome to 1939. Just because Burton drew inspiration from that era doesn't mean anyone in their right mind wants to see Batman asking directions. What's next, a Bat-Gyro?
