Evidence for Unconscious Math, Language Processing Abilities

Next time you're in heavy traffic going 70 mph, try consciously thinking about every move you're making and the move every other vehicle is making or about to make. It will make your head explode.

I know that this really isn't your point, but you touched off a hobby horse of mine.

That's exactly how I drive, if you want to be really safe, it's the only way you can drive.

I'm a paramedic, I routinely drive a 12,000lb (~5,500kg, for those that prefer) vehicle at high rates of speed through maneuvers that are wholly unexpected by a majority of the other drivers on the road, that's the only way I can drive.

I assess every other vehicle on the road, every pedestrian walking along side, and every cardboard box sitting on the curb. I know where they are, how fast they're going, how well they're driving (well, I usually skip that for the boxes.), how likely they are to interfere with my lane space, and as an added bonus, how they're likely to respond to the sight of me in their rear view mirror. From the moment they come into my vision until the moment they leave it, I look at everything no less than once every 5 seconds.

At the same time, I'm also keeping a running evaluation of the degree of urgency I have as it relates to how fast I'm willing to go, how hard I'm willing to accelerate (in any of the three axises available to me), and when and where I have to do what in order to meet those constraints.

That being said, I also drive like that in my personal car (Though I do skip the whole running red lights thing). It's not easy by any means, it requires a great deal of focus, good observation skills and keen geospatial awareness, but it's doable, and it works.

I've driven over half a million miles in ambulances, and probably another half million in my personal car. I've been in two accidents, both of which occurred within a year of getting my license, and both of which I know (as much as you can know such things) that if I could go back and do it again with the skills I have now, I could avoid them. (Oh, and for the record, neither of them were ruled as being my fault at the time.).

Right, sorry.
