Driverless cars could become a reality in five years, and will profoundly affect real estate within eight or nine years. A few possibilities:

• Roughly 15 to 20% of your living space constructed in the average home is devoted to the garage
• Each urban area will have a hub, but it won’t be in the expensive part of town — it will be in the cheaper part of town, right off the freeway
• Fewer parking lots. In 2016, in the D.C. area, commercial underground parking garages added 10-12% to the cost of office construction. In residences, each additional parking space increased the cost of development per unit by 25%. Driverless cars could make these parking lots a relic of the past
• There are 125,000 gas stations in the United States in prime real estate, you won’t need those anymore

10 to 15 years from now, the flying experience could look vastly different because of self-driving cars.

In Europe, high-speed rail wins 50% of all traffic when the journey length is less than 4.5 hours, according to the French National Railroads, and wins 90% of traffic when the journey is two hours or less.

Bags will get picked up in the city and travel separate from you and land at your destination. People won’t be traveling with their luggage. Perhaps it’s picked up by a self-driving car or a specific baggage robot instead.

And if an airline is controlling your ground transportation, it’ll be able to provide other services as well. “They come pick you up, they load your baggage, and potentially, your bag will be screened while sitting in the vehicle.

I don’t know which is more difficult for me to believe: That humans will be on Mars within my lifetime… or that cars will drive themselves. Apparently, both of those things are going to happen and I’m fine with that. “Our republic of drivers is poised to become a nation of passengers,” writes Robert Moor in New York Magazine. Mr. Moor provides a most thoughtful look at where we’ve been and where we’re headed. A few excerpts:

Will middle-aged men still splurge on outlandishly fast (or, at least, fast-looking) self-driving vehicles? Will young men still buy cheap ones and then blow their paychecks tricking them out? If we are no longer forced to steer our way through a traffic jam, will it become less existentially frustrating, or more? What will become of the cinematic car chase? What about the hackneyed country song where driving is a metaphor for life? Will race-car drivers one day seem as remotely seraphic to us as stunt pilots? Will we all one day assume the entitled air of the habitually chauffeured?

Many readers currently blanch at the news that the roads will one day be filled with cars hurtling brainlessly along at high speed. But those people fail to realize one thing: They already are.

Driving correlates with obesity rates, which, separate studies have shown, correlate with poverty rates. Heavy street traffic lowers real-estate values, and the people who live on those streets tend to spend less time outside and have worse relationships with neighbors. Traffic accidents are the leading cause of death worldwide for people ages 15 to 29. Emissions have a disproportionate effect on the health of communities of color, and nearly 90 percent of air-pollution deaths occur in poorer countries. A quarter of America’s greenhouse gases are released by our transportation, imposing a future climate cost that will be paid mostly by the nation’s, and the world’s, least fortunate. Meanwhile, 80 percent of car capacity goes unused, which means that most cars on the road, which can seat at least five people, carry only one.

For those of us who see driving as a kind of imprisonment — which, spatially speaking, it quite literally is — an extra hour to work or play (or eat, or read, or meditate, or fix our hair and do our makeup) will be cherished. But for those who see driving as a physical expression of freedom — which, spatially speaking, it also quite literally is — the end of driving will feel like confinement.

YouTube is going to need a thousand more servers for all the “Look, ma! No hands!” videos once self-driving vehicles become a reality. By some estimates, there will be 10 million self-driving cars by 2020. Shit, if it’s only _half_ that many.

You know the first thing a new owner is gonna do is record video while the car drives itself down the road. People will be eating and drinking (and fucking? Porn.hub gonna need more servers, too).

I’ve seen some amazing technology come along in my 68 years (moon landings, internet, Roombas) but none seem quite as impossible as self-driving cars. If these actually happen, the timing is almost perfect for me. With any luck at all, this tech will be ho-hum by the time I need it.

I am having a little trouble imagining how these vehicles will manage our steep hill when it’s covered in snow and ice but some really smart women and men (with slide rules have thought of that)

As for those “Look, ma!” videos… they’ll get boring soon enough and disappear, replaced by The Next Big Thing.

Shortly before noon I was traveling west on Highway 50 (divided four lane), going about 50 miles per hour. My lane appeared to be free of snow but had patches of black ice (which I guess I always thought of as some mythical substance). There were no cars close to me and I wasn’t changing lanes.

With no warning or sense I was losing control, my Toyota 4Runner seemed to move sideways, off the highway to the right, almost immediately I struck a metal signpost head on. Fortunately some brilliant engineer had designed these posts with hinges so it broke away with just enough impact to deploy the airbags. A good trick for a 17 year old vehicle (thank you, Toyota). A ravine full of scraggly small trees brought the vehicle to a stop.

Called 911 and within minutes local and county folks were on the scene and a bit later the wrecker pulled the 4Runner out. I walked away with a bloody nose from the airbags (yes, I was wearing seatbelt and shoulder harness) and some bumps and scrapes.

I can’t think of much I could have done to avoid this, other than drive a lot slower than 50 mph. My first accident in 50 years of driving and I was lucky. Could have hit another car or something less movable.
