sadly, the idea is an unworkable one for many reasons.
not the least of which, is the amount of computing power that'd be 
required for realtime reactions and calculations.
a computer cannot account for every possible variable.

On 8/08/2009 3:27 AM, Terri Pannett went skydiving, and on the way down, 
shouted thus.:
> The NFB, in my opinion, is off its rocker!  They oppose things which would

> marks on subway platforms, but they want us to drive cars!  Whoopee!  Spend 
> time and money on a dumb project like an adapted dune buggy so a person who 
> is blind can drive a car!
> 
> Aren't there enough sighted drivers on the road who shouldn't be driving? 
> Drunk drivers, people on drugs, people who can't see well enough to drive, 
> people who don't have quick reaction time, people who don't have full use of 
> their bodies and minds, people who don't use the sense they've got people 
> who are too old or too young to drive and you want to add the blind to this 
> group?  The DMV is a joke!  They let people drive who shouldn't be on the 
> road!
> 
> Is this project practical?  No!  Is it stupid?  Yes!  NFB should support 
> adaptive things which would be of practical use instead of wasting time on a 
> dune buggy for the blind!
