self-driving car
If you're like me, your first reaction to the concept of a blind man riding in a self-driving car (toTaco Bell) was probably ... bemused alarm, let's say. Like: "Whoa, cool! Hey, wait a minute ... a blind guy going on a taco run in a self-driving car? This can't possibly end well."
But that's the thing -- it does end well. Really! Because believe it or not, we actually have thetechnology to make this kind of thing happen now ... it's just really, really expensive. Which is sad, because I bet there are lots of other white-haired, legally-blind guys like Steven Mahan who could go for a taco right about now.
Google's driverless car (a Prius) relies on a laser-range finder, which it uses to map out surroundings and respond to GPS signals. The laser-range finder alone runs about $70K -- that's without the cost of the actual vehicle. Dang.
Does it frustrate the daylights out of anyone else that such life-changing technology is available -- but most people can't afford it?
