Sarah,
If you would continue to vote against it after you'd seen the car in
action, I would indeed be surprised.
First, the most common accident sighted people get into is one called
"Looked but failed to see" (LBFTS). In such an accident, the person
did in fact look where the car they collide with was positioned, but
somehow they failed to recognize the car until the collision, or
until avoiding a collision was impossible.
The first prototype from Virginia Tech, a vehicle designed,
assembled, and tested with literally no budget, makes that kind of
accident virtually impossible.
The speed, steering, and object avoidance systems are precise and
accurate. They are the only systems thus far implemented, and a
street-ready car will need more object avoidance systems for safety,
but the proof of concept is there.
The questions are now will future versions of the system be
accurately able to identify and read street signs, can the system
become family-safe, and who is going to make the necessary
adaptations to a GPS (which is wholly not optional for a blind driver
IMO) to make the system work?
The point is that they said it couldn't be done. It has been done.
They said it couldn't be safe. It is safe. There is no illusion
that this thing is ready for the road, of course, but we should
believe now that it can be done. In time, it will be done.
