• Net neutrality: The battle over net neutrality has moved back to Capitol Hill. There are several bills released or in the works that would aim to put compromise net neutrality rules in place after the FCC rolled back regulations that took effect in 2015.

• Self-driving cars: Lawmakers in the Senate have been slowly moving forward with legislation meant to encourage the deployment of self-driving cars, but it's met some resistance from their colleagues. California Sen. Dianne Feinstein said shortly before the end of 2017 that she was holding the bill back from being approved through a streamlined process that bypasses debate on the floor of the Senate because she was concerned about the nascent nature of the vehicles.
