How will your grandchildren get around in wheeled vehicles? (The answer may surprise you.)

And, what will happen to the 400,000 VW diesel cars it has committed to buy back from their owners? (Guess ....)

This is our look back at the Week In Reverse—right here at Green Car Reports—for the week ending on Friday, July 1, 2016.

Friday, two Tesla stories dominated our coverage.

The grimmer of the two concerned a May 7 accident in which a Tesla Model S driver had Autopilot engaged when a tractor-trailer rig turned across his car's direction of travel.

"Neither Autopilot nor the driver noticed the white side of the ... trailer against a brightly lit sky," Tesla wrote, "so the brake was not applied."

The car hit the trailer and passed under it, shearing off the roof, and the driver died at the scene. The NHTSA will investigate the incident.

Earlier that day, our Tesla-owning author David Noland weighed his early 2013 Model S against today's 2016 versions to see how the two Teslas compare in value.

His conclusion: three years later, you get more features—and more electric range—for about the same price.

On Thursday, we checked in with the Indianapolis-based electric-car sharing service BlueIndy to see how it's doing after nine months in business.

Everything's on track, the company says, and it gave us some interesting data on exactly who uses the service—and why.

Wednesday, we noted that even at the fabulous Goodwood Festival of Speed, amidst all the engine roar, there are some green cars to be found.

Well, green-ish, anyway. (Yes, a Tesla Model X was there.)

On Tuesday, Volkswagen and Audi 2.0-liter diesel owners finally learned the details of the Proposed Settlement in the VW diesel emission scandal.

VW will have to buy back (and probably destroy) 85 percent or more of the 466,000 Audi and VW models powered by 4-cylinder diesels with illegal "defeat device" software.

The main question for owners likely to take the buyback was how much money VW would offer for their cars.

But owners of 85,000 additional V-6 diesel cars and SUVs from Audi, Porsche, and VW will have to wait until August 25 for a status update on a possible settlement for their cars.

Apparently Volkswagen thinks it can modify those diesel vehicles to comply with emission limits. If so, it's unclear whether buybacks would even be offered.

We kicked off the week on Monday by looking decades into the future, at how your grandchildren will get around in wheeled vehicles.

One firm's report suggests that not only will they not have to fill their gas tanks—there won't be any—they won't even own cars.

Finally, we noted this week that Elio Motors, which hopes to launch an "84-mpg" three-wheeled car for $6,800, issued a breathless press release saying that has built a car.

One test car, in fact. Golly.

Those were our main stories this week; we'll see you again next week. Until then, this has been the Green Car Reports Week in Reverse update.
