Comment: Target For Terrorists (Score 1, Flamebait) 117
This seems like a very cool idea, but I can't help but think that any system like this that goes "widespread" will be a prime target for crackers looking to do a little terrorism. Seeing as many public-use devices--pacemakers, and others that have been reported on Slashdot--utterly fail to be secure against such attacks--and since this one requires wireless receiving wireless signals in order to function, it's only a matter of time before an enterprising "cyberterrorist" decides to cause a pileup. Therefore, I question the wisdom of enacting such systems, even though the technology is cool, and could be very helpful if it worked properly (and reliably).
I often wonder if a Shweeb-like system, modified with partial motorization for long stretches of (high-speed) highway, uphill areas, etc. might be a more sensible approach. Sometimes advanced technology doesn't make things "better," despite how fun it is to think so.
