Driverless cars continue to pick up steam, yet technology is not the only factor in the future of autonomous vehicles.
Congress and lawmakers will likely play a major role in the progress of these cars, even as Uber and Google's Waymo are testing vehicles in different cities across the nation.
According to the National Highway Traffic Safety Administration, 94 percent of crashes in the U.S. are due to human error.

The NHTSA believes automated vehicles have "great potential" to save lives, suggesting it's all dependent on allowing a greater number of test vehicles on the road.
And that's all dependent on Congress.
According to The Hill, federal law only allows manufacturers to test 2500 vehicles that are exempted from road safety standards — in order to test the safety of the vehicles — on the road per year.
As the industry for autonomous cars continues to grow over the next several years, lawmakers will likely have to examine regulations such as this cap.
Though proponents of autonomous vehicles believe new tech careers will emerge from its creation, critics are concerned they could lead to job losses.
