Don, I defer to your experience in the handling department - perhaps the liveliness I feel in my iMiEV is simply due to the minimal contact patch :roll: , yet I consider the iMiEV very stable at speed. However, when it comes to mileage gain, I believe there were a number of tests which showed a significant improvement at higher tire pressures. For example, I briefly looked at EcoModder and they repeated the Mythbusters results as being a 7.6% reduction in fuel consumption in going from 35psi to 60psi:

Translate that 7.6% into a range increase and that gives us close to five more miles of range for the iMiEV.

My Gen1 Honda Insight lifetime of over 77mpg isn't only due to featherfooting.

Nevertheless, as you pointed out, we don't want anyone to treat this as a recommendation to exceed the manufacturer's tire pressures, which are posted on the driver's - side door.
