It saddens me to say it, but we are approaching the end of the automotive era.
The auto industry is on an accelerating change curve. For hundreds of years, the horse was the prime mover of humans and for the past 120 years it has been the automobile.
Now we are approaching the end of the line for the automobile because travel will be in standardized modules.
The end state will be the fully autonomous module with no capability for the driver to exercise command. You will call for it, it will arrive at your location, you'll get in, input your destination and go to the freeway.
On the freeway, it will merge seamlessly into a stream of other modules traveling at 120, 150 mph. The speed doesn't matter. You have a blending of rail-type with individual transportation.
Then, as you approach your exit, your module will enter deceleration lanes, exit and go to your final destination. You will be billed for the transportation. You will enter your credit card number or your thumbprint or whatever it will be then. The module will take off and go to its collection point, ready for the next person to call.
Most of these standardized modules will be purchased and owned by the Ubers and Lyfts and God knows what other companies that will enter the transportation business in the future.
A minority of individuals may elect to have personalized modules sitting at home so they can leave their vacation stuff and the kids' soccer gear in them. They'll still want that convenience.
The vehicles, however, will no longer be driven by humans because in 15 to 20 years — at the latest — human-driven vehicles will be legislated off the highways.
