The timeline for driverless cars

We know they’re coming, but how long it takes them to get here really matters.

For Elon Musk, the driverless car is always right around the corner. At an investor day event last month focused on Tesla’s autonomous driving technology, the CEO predicted that his company would have a million cars on the road next year with self-driving hardware “at a reliability level that we would consider that no one needs to pay attention.” That means Level 5 autonomy, per the Society of Automotive Engineers, or a vehicle that can travel on any road at any time without human intervention. It’s a level of technological advancement I once compared to the Batmobile.

Musk has made these kinds of claims before. In 2015 he predicted that Teslas would have “complete autonomy” by 2017 and a regulatory green light a year later. In 2016 he said that a Tesla would be able to drive itself from Los Angeles to New York by 2017, a feat that still hasn’t happened. In 2017 he said people would be able to safely sleep in their fully autonomous Teslas in about two years. The future is now, but napping in the driver’s seat of a moving vehicle remains extremely dangerous.

In the past, Musk’s bold predictions have been met with A-for-effort enthusiasm and a smattering of polite skepticism. But the response this time has been different. People have less patience for PR campaigns masquerading as engineering timelines. “That’s bullshit,” says Sam Abuelsamid, a research analyst for Navigant, a consulting firm that ranks companies on the viability of their autonomous vehicle plans. “At best, they may be able to create a system that functions under certain limited scenarios. It will not be fully autonomous in 2020 or anytime in the next several years.”

What’s changed? Self-driving cars—and their associated building blocks such as machine learning, computer vision, and LIDAR—continue to improve, but executives other than Musk have been admitting that reports of their impending deployment were greatly exaggerated. Ford CEO Jim Hackett said last month that the industry had “overestimated the arrival of autonomous vehicles.” Chris Urmson, the former leader of Google’s self-driving car project, once hoped that his son wouldn’t need a driver’s license because driverless cars would be so plentiful by 2020. Now the CEO of the self-driving startup Aurora, Urmson says that driverless cars will be slowly integrated onto our roads “over the next 30 to 50 years.” That’s nearly as long as it took computers to evolve from IBM’s first mainframe to Apple’s first iPhone.

I touched on this recently in the context of ridesharing companies and their existential future, which is based in part on self-driving technology. I’ll say again, the prospect of driverless cars has an effect on current policy debates. If you believe they will be in common usage in the next five to ten years, then it’s reasonable to expect that they will begin having a significant effect on driving habits and traffic patterns in the short term. In particular, this argues for a change in approach to how we invest in infrastructure and mass transit. As that link suggests, why spend on rail projects when you can build souped up HOV lanes that will accommodate autonomous buses that travel at 80 to 100 MPH?

But if we’re on a thirty to fifty year horizon, then basically nothing has changed and we should proceed as if driverless cars are no more a part of the landscape than the flying cars we were once promised. Fifty years is forever in infrastructure terms. Hell, thirty years is a very long time. All but six MLB stadia are thirty years old or less, and many of the new stadia replaced other facilities that were between 30 and 40 years old. I’ve lived in Houston for 31 years, and every single highway in this town has been substantially rebuilt during that time frame, some more than once. The same argument about whether or not to invest in light rail should apply to the planned mammoth rebuild of I-45, which last I checked isn’t geared towards high-speed robot buses. I say nothing is worth delaying or deferring for a possible future with a timeline that may be measured in decades. I guarantee this issue will come up when the Metro referendum is officially put on the ballot. I’m happy to discuss how we should integrate autonomous vehicles into our traffic and transit planning, but let’s keep this in mind.

    The driverless car will be as popular and successful as Google Glass. Which is to say, not at all. If it is, it’ll be so far in the future we might as well discuss flying cars while we’re at it.

    I cannot believe grown, educated, supposedly smart people in Houston are holding up current transportation options because driverless cars are coming.
