Summary:

• **What Tesla is asking for:** A Tesla executive spoke to the U.S. Senate about self-driving cars and asked the government to create clear rules for how autonomous vehicles should work. Right now, different states have different rules, which makes it confusing for companies trying to build and test self-driving cars.

• **Why this matters:** Self-driving cars are a new technology that could make transportation safer and easier in the future. Before these cars can be used everywhere, the government needs to decide on fair rules that all companies must follow, similar to how there are rules for regular cars and drivers.
