There are only two people-movers outside of airports in the united states. One is in Miami, the other in Detroit. Both have been around since the 80s.
Meanwhile, trams are coming back in cities across america- Detroit, Milwaukee, Denver, etc, etc, etc and it's all very recent- starting in the mid 2010s.
Your perception is quite false. Frankly, I'd like to see more of both. I think people movers and trams compliment each other beautifully.
Also, it's quite humorous to me that it's covered in Fishbone's ad's since I used to cook there on Jefferson.
