As a mechanically astute person I can tell you this is total garbage.
What happened to the local garage is two things.
1) Reliability has been increased considerably. There are now cars that go 100,000 miles without requiring a tune up. In the past this was not the case.
2) The complexity of automobiles has increased to a point that precludes "shade tree" schmuck's with just hammer's and screwdriver's from repairing them effectively.
Thus, "gas pump laws" are not going to bring back the local garage.
This whole thing is insane, what's next "soap on the shower floor" laws?
