Re: "is there any way to reduce the hopping
motion created by uneven interstate roads?"<br><br>There
are, indeed, a couple things you can check. Although
the manual suggests 35/33 psi, most people find they
get a better ride at 40 - 42 psi. The stock Potenza
tires have a max psi rating of 50, so this is
reasonable. (But make sure your "used" car still has tires
marked max psi 50 before increasing
pressure.)<br><br>Several people have claimed that they had bad highway
control due to incorrect alignment setting. In
particular, toe-in needs to be close to 0.1 degrees (that's
total, preferably 0.05 degrees per
wheel).<br><br>Finally, though we don't seem to have the problem on the
roads I normally use, I have driven in places where
trucks travel fairly consistently at one speed. The road
develops a regular wear pattern that causes oscillation at
particular speeds. Usually, a change in speed of +- 5 or 10
mph will eliminate the oscillation. I haven't been on
a road with this condition in a Prius, so I can't
speak to Prius specifics.<br><br>Re: "Do you think that
we could retrofit the daytime head light dimmer
also?"<br><br>There's a substantial difference in wiring pattern
between DRL and non-DRL headlights on the Prius. Toyota
does not (currently) offer a retrofit package. You
might be able to do it yourself, but you need to be
very careful. It would be rather easy to accidently
miswire things to cause short circuits/fires/lack of
headlights at odd times ...<br>You would need to carefully
compare the two wiring diagrams to be sure you didn't
miss any of the subtle differences. Personally, I find
it easier to just turn on the lights in the daytime
if conditions warrant. They're only 10% brighter
than the DRLs, so I don't see the big draw to slightly
dimmer lights that can't be turned off even if they're
annoying someone.<br><br>Re: "The salesman gave me a
sticker that came with the car. It says, "Eat My Volts."
Did everyone get one of those?"<br><br>Toyota, USA,
intended that each Prius come with one of these stickers,
but they weren't 100% successful at providing them. I
think that most of the target population for early
adoption of the Prius find this sticker to be a bit too
"in your face", so I don't think all that many found
their way onto the cars.<br><br>Good luck with your new
Prius!<br><br>Robert Snyder<br>NJ-PIKACHU
