 That is the key, isn't it, naperlou? Right now, the technology forces the driver to look down, instead of ahead. Someone needs to do a study on how long it takes your eyes to look at the display and then re-focus on the road ahead. In vehicles, I think it's always been assumed that it takes 0.4 seconds for a driver's eyes to look down at the speedometer and then return to the road. Head-up displays were able to reduce that figure. A bike, however, goes slower than a car, so the readjustment time doesn't translate to as many feet travelled.

I have a few Raspberry Pi boards... I only wish they had a little more power. Something on par with the recent Smartphones. Then the Pi would be a DIY behemoth. PIC/ARM/and Arduino dev boards still rule the roost for the most part.

Also, aside from a head's up display, I hope they add some way to project warnings on the road to alert automobile drivers. Then, they have a great HUD system for bikes..

If we're talking about commandeering the brakes and steering, I don't see why it can't be done, JMiller. We just need to wait a few decades for the costs to come down.

@jmiller, you raise a good question. Perhaps the speed could just be displayed on an LCD. What is more important in cities is to see jerks behind you. Perhaps we need a rear-facing camera that flips the image right/left (as a mirror would) and displays the picture above the handle bars. Hmm, but why not just use a mirror? Maybe some value add could be brought in here using the Raspberry Pi that a mirror could not -- other sensors perhaps.

I think there are already plenty of different options that help maximize our vision and things like that.  I see this and other improvements that are an effort to extend the current human abilities.  Stop the bike faster than a human.  Or see something that humans can't see.  Make a prediction on the facts or surroundings that cause a precautionary response faster than we as humans can do it.  I think it's possible but wonder about the costs and value.

I also wonder what it would feel like to have a bike brake or steer without me knowing or predicting what it is going to do.  Would it just wipe me out?  Don't know but will be interesting to monitor.
