Check out this interesting article of how transportation changed in 2015: Bike Sharing, Driverless Cars, And Hyperloops: 2015 In Transportation
"2015 was the year we continued to see new types of transportation, including self-driving cars and buses, all kinds of drones, and even futuristic trains, like Elon Musk's Hyperloop .
It was also when we started to see transport become better integrated. Bike share companies looked to become part of wider transit systems (rather than just standalone services). Uber started to share data with cities, auguring a time when ride-sharing become part of public networks. And, we saw plenty of new apps and sites allowing people to move more seamlessly between modes. For any given journey, we can now understand the best way to get from A to B.
There were some failures as well. Leap Transit, an upmarket private bus service in San Francisco, went out of business (not that anyone minded too much). Generally things got better. As we gather and crunch data more effectively, we should be able to move more quickly and with less hassle, even as cities become more congested with people."
2015 was a big year for transportation, it is amazing to look back and see everything that was done!
