I will die before I buy another car.

I don’t say that because I am particularly old or sick, but because I am at the front end of one of the next major secular trends in tech. Owning a car will soon be like owning a horse — a quaint hobby, an interesting rarity and a cool thing to take out for a spin on the weekend.

Before you object, let me be clear: I will drive in cars until I die. But the concept of actually purchasing, maintaining, insuring and garaging an automobile in the next few decades?

Finished.

This could be the most important shift since the Cambrian explosion of the smartphone. Car-sharing continues to increase (Uber and Lyft are set to go public this year), new innovations emerge all the time (Scooters! Vertical-take-off-and-landing vehicles!) and all manner of autonomous technologies are inevitable (Elon Musk, whatever you think of him or the prospects of Tesla, is 100 percent directionally correct). Private car ownership declined globally last year, and it is a trend that I believe is going to accelerate faster than people think.

Not everyone agrees. After an initial rush of hype and hope, there was a backlash against the idea that autonomous and shared cars would soon take over.
