Intrigued for two reasons:
1) I'm reminded of DFW's words about shopping at large stores playing 'soul-killing musac': https://www.youtube.com/watch?v=8CrOL-ydFMI#t=10m8s This is going to make life easy for me. Grocery-shopping is stressful and time-consuming, I look forward to the day that I can do it all online without paying much extra.
2) Less people will need cars in the future of AmazonFresh/Grubhub/Blueapron. This is also why I love Uber pool incidentally... I feel like I'm saving the environment when I do that (vs. driving)! If you continue in this line of thinking, what you have is: one truck delivering 50 people their groceries via an optimized route vs. 50 cars traveling by stressed out people who are tired and just don't want to go the store. Less accidents, less pollution, less stress.
I am really looking forward to the future of optimized infrastructure for travel/transportation.
