In a taxi in NYC, on the way to the airport, I noticed this sign on the door.
Despite the sign, when he stopped to let me out, he immediately explained, in a difficult to understand accent, “Push the lever, then pull the door”. It took 3 tries, but eventually I was able to get enough leverage on the red lever to push it down, which then made it possible to open the door.
The problem here isn’t so much the labels, it’s the lever. Unlike some vans, it’s not a button you simply press in with one hand as you grab the handle. The lever is high and far enough you can’t activate it as you grab the door.
