What do we think of the PUMA, from GM and Segway?

I am particularly impressed by the tie-in with OnStar as a "v2v" (vehicle to vehicle) control system. To my mind, this makes the long-term PUMA concept doable, something more than a splashy gimmick that will magically disappear once GM gets its bailout money.
While not public transit, I believe Neighborhood Electric Vehicles don't require licenses to operate, so it lowers one access barrier to better transportation. I could easily see local transit agencies contracting to rent fleets of PUMAs to expand rail station ridersheds.
The major hurdle PUMA has to overcome is how they will safely mix in traffic with regular automobiles. I wonder if they could be so popular that onstreet bike lanes would have to be converted to Bike/PUMA lanes.
