The EFF has a post about the proposed "Right to Repair" law
that would stop the practice of car companies locking up diagnostic codes and information in onboard car computers.
These codes have been used to force car owners to go to dealers, rather than independent car repair shops, basically using the DMCA to backstop the plan. This is (of course) an abuse of the DMCA in many ways (it wasn't intended for this purpose at all). So while it's good to see this bill put forth to deal with this specific problem (and, as the EFF notes, amazing to see the Libertarian Party and the Green Party both sign off on it), the real issue is the fact that this bill needs to be there in the first place -- and the fact that it's only limited to car repairs.
Ideally, the solution would be to get rid of the DMCA's anti-circumvention rules, but the EFF suggests a more universal "Right to Repair" Act. I'd even take it a step further and say, why not a "Freedom to Tinker Act"? This goes beyond just "repairing," and to basic tinkering -- which is often found at the root of innovation. Companies are abusing copyright law in many ways to prevent any kind of tinkering whatsoever, beyond just repairing. Doing so clearly goes against the entire purpose of copyright law, and it would be great to stop that kind of abuse.
