This whole three bars thing concerns me and I may be shooting a bit from the hip since I have not done my homework... to me, it's this simple... first start of the day, start the car... let idle a minute or so to get all pressures up and fluids circulating to the right places... drive the car conservatively until it completely warms up to normal operating temp... so, what's "normal?"
If the temp guage measures water temp the three bars don't cut it form me... it's oil and engine temp that I look out for... if the temp guage measures oil temp the three bars thing is a bit easier to bite off on...
I say, start it, wait a minute, drive it nice and easy until you know everything in that motor is up to operating temperature. Hammering an engine that isn't up to temp is one of the worst things you can do to it. Slow warm up ritual lets everything else in the car come up to temp as well... tires, brake pads, tranny, even wheel bearing grease... maybe I'm a bit anal but I have built or help build a few race motors and this was our SOP for our street and track cars.

I start the car, fit my belt and reverse out the garage, then drive gently until I get out of town and gradually wind it up. Cars warm up quicker on the move, and it won't rev hard when it's cold anyway. And I don't have time to waste sitting still.

if temp < freezing, wait 15 seconds
else, wait 5 seconds
drive off, keep RPM below 3500
while (temp gauge < 3 bars) loop
drive 3-5 miles

the owners manual says specifically that you do not have to wait to start driving. so if you do wait, fine, but don't act like you're doing something better than the rest of us... unless you want to explain to everyone how you know the s2000's engine better than honda.

This is because the heads are aluminum and must expand slightly within the chambers so they dont rattle before warming.
You can tell people who start engines then rev them and take off after a couple years the heads have ripples down inside the chamber walls.
