The diff and tranny need to warm up too
BTW, when the car sits and idles in neutral, the tranny is spinning also. This will warm up the tranny but nearly as well as if it was under load. The rear diff, propshaft joints, CV joints, however, will still be stone cold. Even a short, sedate drive out of the neighborhood will warm those up nicely.
I like to get out and stick my tongue on them, if it hurts, you're good to go!

personally, i drive the car as soon as the motor is on. i keep it under 4000rpm and half-throttle until i get a nice full warm-up (~8 bars? or whatever the standard operating temp shows)... then i rip into 'er

Here is a passage from my owner's manual, p.121. Try reading it sometime.

I drive the car within 10 seconds after starting the engine, but I kept it under 3000rpm the first 2 miles, under 4000rpm the next mile. 3000rpm in sixth gear is about 55mph, which is very fast on city streets.

Dave, you are forgetting that most of the S2000 owners on this board learned how to drive 40+ years ago, when it was advisable to warm up the engine before driving off. Otherwise I have no idea how people get the idea that they must warm up their ECU. Or maybe the people here just don't know how to read?
Of the 4 people in this thread alone, 2 are aged 20, 1 is 23 and the other is 27.
Like you say, I started driving 42 years ago when carbed cars needed to be warmed up till you could "kick down" the high idle. But you won't see me warming up a fuel injected car that's run by an ECU.
Maybe the "younguns" have been listening to their dads too much.

I still catch myself trying to kick down the high idle every once in a while. I blip the throttle and then think "oh yeah, modern car". At least I don't pump the accelerator before I start it.
