In practice, automobiles would roll no faster than 25 mph in residential
neighborhoods, assuming non-psychotic operators.

12 mph would be about a 2 hour 11 minute marathon.

12 mph is a pretty good speed for loaded touring, and a lot of urban
commuters in these months are down at that speed. (well, I am anyway -- it's
icy and dark)

I'm beginning to feel fast and arrogant about my commuting, though i do
have a relatively short commute (30-35 minutes). I _average_ nearly 20
km/h, which is faster than 12 mph, and I have a very non-flat commute,
with plenty of traffic lights.

It's not icy right now in Vancouver, but dark we have!

Still grumpy, still riding the crappy doesn't-fit mountain bike, still
waiting to get my good fits-okay road bike back,

errrr...20 kph is ~12.5 mph

Maybe you meant to type 30 kph?

No, but I forgot how close it was. That said, I stand by my statements:
20 km/h is faster than 12 mph, and while it isn't a great average speed,
I have some pretty substantial hills on my commute, and getting 2 km
without having to stop for a light on this ride is a real piece of luck.

Okay, okay, I'll start riding faster.

Hard to say. Kamen's previous invention ("Fred" to Segway's "Ginger")
was a very trick wheelchair using similar technology. It's fair to say
that when you're getting an electric wheelchair certified, they're
pretty picky about stability.

One of the stock demos of the wheelchair (which had a mode where, like
the Segway, it rode on two wheels) was a "sumo match" in which one
person would attempt to shove the wheelchair-user. The wheelchair kept
its balance and position despite rather hard shoving.

How that translates into a bump or a curb hit (well, a curb hit is goin
to hurt, I think we can agree) I don't know.
