H.R. 1566 is a rule that says car owners can learn about and fix their cars however they want, without the carmakers hiding or controlling the information and tools needed for repairs. This lets people choose where to fix their cars, like going to any mechanic they like, and using any parts they want.

S. 1379 is a plan to make sure people can see and use all the important bits and pieces to fix their cars, so they don't have to go only to the car maker. It wants to make everything fair and easy, with help from a group that checks if it's working well everywhere in the U.S. without getting too puzzling.
