In my future world patterned as a dystopia of Western society, I want cars, more or less as we have them today (four wheels, metal crush cage with weathertight windows fully enclosing passengers, driver required at least for some of the trip, some sort of mechanical powerplant whether ICE, fully electric or hybrid). The number of cars will be minimal for a number of reasons, but I don't want one of those reasons to be that technology is moving human transportation beyond that point, especially for the super-rich; that makes my use of a car anachronistic.
About how much longer, in your estimation, will passenger cars exist in a form that a 2015 human would recognize as such? Obviously styles will change on a cycle of 5-7 years, and DARPA and other government agencies and NGOs have been directing manufacturer efforts on self-driving cars, but even many of these guys say a fully self-driving car is still decades away, primarily because a driver needs to be there for all the edge cases that confound the computer (bad weather, construction detours, unimproved roads, etc).
Even if the car is semi-autonomous, able to follow a route on freeways but requiring a human driver to negotiate driveways and parking, four wheels on the ground, a steering wheel in the driver's hands and a mechanical engine to power it all has been a staple of the machine since its invention, with a sturdy metal shell to protect driver and passengers since about the '30s; how much longer can we expect to have these elements in an individual passenger transport?
