To put it bluntly, raise your hand if YOU want to be the first car manufacturer to make a car for which you are potentially liable in *every single accident that car ever gets into*, from the day it's sold until the day it's scrapped. Any takers?
... no one. But you'll get plenty who charge mandatory tune-ups to ensure compliance. The question will be "which company DOESN'T charge a fee for a mandatory yearly check-up"?
Asimov's early robot stories dealt frequently with corporate liability and it was often the source of the plot conflicts. If a proofreading robot made a mistake causing a slander ("Galley Slave") or an industrial accident resulted in injury, US Robotics was put into the position of having to prove that it was not the fault of the robot (which it never was).
This is why Asimov's US Robotics didn't sell you a robot, they leased it to you. The lease was iron-clad, could be revoked by either party at any time, had liability clauses, and had mandatory maintenance and upgrades to be performed by US Robotics technicians. If you refused the maintenance US Robotics would repossess, sue and claim theft if you withheld ("Bicentennial Man", though unsuccessfully; "Satisfaction Guaranteed").
A properly functioning robot would not disobey the three laws, and an improperly functioning robot was repaired or destroyed immediately ("Lost Little Robot"). Conflicts between types of harm were resolved using probability based on the best information available at the moment ("Runaround"), and usually resulted in the collapse of the positronic brain when it was safe to do so ("Robots and Empire", etc.).
