Now it's certainly possibly that sharing will reduce the number of cars sold, and electric cars may increase their lifespan. But with massive increases in usage, I don't think it'll make much of a dent.
What may affect behavior is tech that significantly lowers the cost of sharing, like Uber et al.
Ultimately I think most people will still own their own cars: it is nice to know your golf clubs are in the car just in case you can take the afternoon off. It is nice to have a change of clothes in case your kids "has an accident". It is nice to have all your reusable bags in the trunk just in case you decide to stop for groceries after work. I've started taking the bus, even though I never actually need to do those things I miss them.

We’re going to add another 2 billion people and the world is getting richer. What do you think that will do the car sales?

EDIT: More specifically on car sales, they do mention a decline in China: "IHS sees the biggest impact of mobility services coming in China. Auto sales there plunged 18 percent in January, an unprecedented seventh consecutive monthly decline, as commuters rapidly embraced ride-hailing."
“Researcher IHS Markit predicts the 100 million vehicle milestone will be surpassed in the next decade, but only because of growth in China, India, Russia, and other emerging markets”
China is already a much bigger car market than the US.
They are also experiencing a bit of an economic slowdown, probably cause by the trade war.

We will have less cars, but each car will spend more time on the road. Currently most car are idle day and night in parking, being driven around 2 H/day (less for many many cars). Some families now are starting to use 1 car for the family + car sharing for everyone instead of 1 car per family member. If you combine that with self driving cars in around 10 years, the money will be made by the car makers making very reliable / sturdy cars for the driverless taxi companies.
"It's no longer worth while for us to keep up our original models, so we're turning them all off on January 1, 2021. All owners will receive a $2000 credit toward purchasing a new vehicle....".
That's how it goes when you're buying a service rather than an object (see also: DRM books, etc.).
CERTAINLY there will never be a 60-year-old Tesla. Can't legally maintain it, can't drive it without Tesla's support, and they won't.
There are people who still own fully-functional Ford Model T's from ~1910. They are over 100 years old, and they still drive them through the Memorial Day Parade every year.
Yes there will. It will sit in some rich guy's garage, hacked up to function without mothership contact, and specialty publications will publish pictures of it every few years.
I'm not sure if this is intended to be hyperbole or just extreme pessimism.
If Tesla decided to just "shut off" everyone's car for being too old, they'd be hit with a class-action lawsuit as soon as a lawyer drafted it.
At worst, they could decide to stop manufacturing parts, but even that's unlikely, as parts could still be sold for profit to people that need repairs. I know right now there's long waits for replacement parts, but that's due to production prioritizing building more cars to be delivered, not for providing replacement parts.
