I love that this is how you thought through this problem! Your words are perfect here — “Ah Ha! Good Question! That is what makes product design fun!” You are correct in the endless possibilities with your core solution to such a tremendous pain point in the Uber experience. I went through the same experience while visiting Chicago. I had an uber driver tell me that he had someone try to get into his car right before my friend’s and I got there..LOL! This would be brilliant, I hope they take a look at your article here.
