Automated cars from Minority Report

The post mentions several times how it's both costly for adopter to add infrastructure to support robots but also how other forces can make that infra already there e.g. how it costs money to install wifi in a warehouse but handheld scanners led to wifi being in them anyway (which was great for the robots too). This reminded me of a quote about the future of automated driving (paraphrasing): "We currently consider the following to be distinct and very different modes of transportation: - car - elevator - train At some point, those will all converge into a vehicle that can travel on roads (like a car), with other vehicles (like a train) and bring you up to a building floor (live an elevator)." This seemed somewhat true to me until I considered two things: 1. The smart phone did something similar with a phone, television, computer etc 2. There is a scene in the movie Minority Report that does exactly what the author of the original quote described. [0] The combination of another convergence device AND a fictional visual of what that convergent device would like really hammered home what the future might look like. 0 - [this video]
