When the right wheel bounces upward six inches going over a bump, does 
it have no effect on the left wheel at all? It's really a 
SEMI-independent arrangement, right?

The P6 suspension is cool and seems to work well, but the simpler SD1 
suspension seems to work well, too. In a practical sense (as in what you 
feel when you drive the car, ride, control over uneven surfaces), how is 
the P6 superior to the SD1? Is it enough to be worth the complexity and 
expense? The SD1 seems to get pretty high marks for its rear suspension 
in terms of how it actually performs on the road, and I know from 
experience that the back end of an SD1 feels pretty securely planted.
