As one who now regularly drives the i-MiEV at its upper limit keeping with the flow of traffic on local freeways (a necessity in the HOV lane so as not to become a road boulder), I have a few observations -
1. Not much different than driving any small car and being buffeted by crosswinds or big rig backwash.
2. The minimal (zero?) toe-in makes the car susceptible to wiggling on longitudinal grooves in concrete roads. Perhaps something to do with the LRR tires as well?
3. Hitting a rough road patch on a long sweeping downhill curve activates ASC which is disconcerting the first time one experiences it (especially at high speed), but you get used to it.
4. The car is always fully controllable, no matter what. If one does stupid things, ASC kicks in.
Off-topic, but allied, the car's very low center of gravity makes it a joy to toss around twisty winding curvy roads, and I inevitably catch up to muscle cars that roar away initially...
I nowadays keep my tire pressure around 40-42psi, although still prefer the unacceptably-high 60psi overpressure for mountain road driving.
