The unfortunate part of something this transformative is the inevitable, ardent stupidity which is going to erupt from the general public. Even if in a few years self-driving cars are proven to be ten times safer than human-operated cars, all it’s going to take is one tragic accident and the public is going to lose their minds. There will be outrage. There will be politicizing. There will be hashtags.
If a tiny winch was stuck at the wrist with a super thin wire leading up to the tip of our index finger, it could simulate a surface by straining and retracting the wire at just the right time and thus giving haptic feedback in mid air. This would create an “air tap“, simulating a surface that doesn’t exist.
