[citation][nom]JMcEntegart[/nom]Segway and GM seem to be pushing this towards really big cities where subways, metros, trains etc are usually pretty decent but people are driving everywhere anyway. Aside from the fact that the PUMA can only do 35 miles on one charge, congestion is less of a problem in smaller cities and towns and so, there's less of a need to scale back the number of cars on the roads. I'd also be concerned about the accidents these would likely be involved in if they were out on roads with less traffic, ie faster drivers. Scary.[/citation]
In the US, we're going to see a lot of urban flight now that the economy is entirely in the toilet. It makes this that much less relevant, here. In Japan or the UK, where cities are geographically denser, it might be useful.
While public transportation ridership in the US has increased in the last half year or so, people will never give up their cars. GM really needs to get its head out of its ass and invest in viable, practical, and profitable research and development.
