Actually the physiological effects of lead had absolutely nothing to do with its removal from gasoline.
It was the fact that is would screw up the catalytic convertors on cars. Lead abatement in paint, apartments and all that was a totally separate issue.
And if your kids are eating paint chips off the walls, you might want to watch them better, or possibly feed them better. Remember, they pick your retirement home.
On scary battery plants or MBTE exposure, or long-term lead exposure rates?

I imagined you visited some dirty smelting town where everybody was a mouth breather caked in filth. The battery plant must have been a pleasant place too.
Gary, IN had the permanent pollution cloud over it from heavy until maybe the early 2000s. The smell was awful.
The battery plant was in a town called Leeds, Alabama, and I have no idea what happened to it. I was born in Pittsburgh so I have a pretty high tolerance for industrial waste in the air, but lead is scary. The company there had sent recruiters to gatech and as a new grad I was trying to get as many plant tours as possible just to see what the industry was like.
I still do try to get plant tours whenever I can.
Here is some recent but pretty complete data on lead levels in children:
And here is a good overview on why any lead is bad:
I don't have a good online citation on how blood lead levels dropped when leaded gasoline was banned, but "Cities: An Environmental History" has an overview.
But if it was anything like Pittsburgh, the sunsets were beautiful. My aunt is still upset that they closed the mills down and now with no sulfur in the air she keeps getting mildew on her roses.

Yeah. Do a buyback and sell them where it's bloody hot
3rd world countries in africa and asia would rejoice (australians would too I'm sure)
The proper fix would be to buy the cars back from the (willing) owners at bluebook and sell them to the (3rd world) countries that do not participate in the smear campaign against VAG and could not care less about the emissions. An even more proper fix would be for VAG to withdraw from the american market altogether. There are lots of other markets where you do not have to make emissions claims at all and that would appreciate the 4 banger [turbo]diesels from VAG

According to NBC, the emission controls were altered when only the front wheels were turning, as on a dynometer.

I don't know about diesels, but newer gasoline powered cars in California don't use the dyno anymore. The levels are all read from the sensors via the OBD-II port, at least in California.
It's trivial to detect that the car is not being driven. No steering wheel motion, no compass variation, no accelerometer (if fitted), no... you name it, I'm sure there's a long list of candidates.
YOu're overthinking it. It's about driveability If the rear wheels ain't turning, you should turn on the emission controls. When the car is stopped in traffic, might as well make it clean. Performance isn't an issue when stopped. I'd have taken it a step further and made it clean whenever driveability isn't compromised...like when not accelerating at a rate faster than you could do with the emission controls functioning. Probably would never have been detected.
