IOTA is integrating themselves into automated car systems and using their Tangle architecture and platform will allow vehicle to vehicle communication on a mass scale in the future. Iota also plans to have these cars operate completely independently and have cars themselves pay tolls and parking meters, allowing for a hands-free transportation experience.
IOTA is also currently being integration into a few floors in the Taipei building to track fill levels in their waste bins and in the future help provide for more efficient city design and ways of living. These are big markets in the future and I think IOTA will be ahead of the pack when it comes to these things.
