Aye, it'll cause cancer of the foot it will.

I think just about all new cars have "throttle by wire" now, but I may be
wrong.

The throttle has no mechanical connection to the fuel injection system
as in the old days with cables and/or linkages. The throttle position
is measured electronically and this is read by the engine control
computer which then controls the throttle plate position via a motor and
the fuel injector via PWM, at least this is what I believe is the case.
I just got my service manuals a couple of days ago and haven't studied
this in gory detail yet.

I'm not worried about mine in the sense of it going bad, although I do
trust a cable more than rheostats and motors. My complaint is that the
throttle is overly sensitive and lacks the tactile feedback present in
mechanical throttles.

I think so too Eric. The first trip I took of any length (125 m) with
temperature above 60 F , my mileage went up by 2+ mpg (28.5)

Temps and fuel economy... and tire pressure. I'm starting to think
tire pressure is a significant part of the cold weather equation (tire
pressure can drop with the temperature). Winter average on my 06 was
down which was not a big surprise. On a day in the 30s I checked tire
pressure and found the tires down about 3 or 4 psi. After returning
the tires to 30psi I noticed my fuel economy is back to averaging above
21 mpg on two recent tanks.
