Default Toyota/Lexus: Driving in "S" mode for automatic transmission?

For any of the more recent, newer Toyota/Lexus (maybe Scion, too?) with the gated (zig-zag) gear-shifter thingy (specifically, for the 6-speed automatics) that read "PRND" and then to the left (or right?) of "D" with a separate "S" gate with "+"/"-" up/down for on-demand up-/down-shifting...

Can you leave the selector in "S-mode" and drive as-is? Does it hold gears while waiting for you to upshift or something and overrev bouncing the tachometer needle up and down like crazy to risk engine blowing up into pieces? Or, does it allow the computer to take over and override the low gears by upshifting on its own? From there, will it also downshift on its own at the appropriate times?

Basically, will the car drive on its own just fine by leaving it in S-mode? If so, will the driving experience be different from driving in "D" (normal mode) in terms of throttle response, acceleration, upshifting/downshifting, cruising, braking? How so?

And how do you turn the overdrive on/off on these things? Is it "automatically" taken care of for you?

With manumatics generally, they'll stay in the gear you left it in until the last possible second, when the computer senses that Something Is Screwy. This is the antithesis of "just fine.""Overdrive" as a word is overused. Basically, any gear in which the ratio is less than 1 is an overdrive. Fifth and sixth on a six-speed Toyota will be overdrive gears.

My advice: leave it in D unless you need to run in a lower gear for more than a few seconds, then kick it over to S and pick the one you want.

Simply you cant leave it on S mode because it redlines

each gear and you will be sitting there redlining and potentially

blow your engine if the computer doesnt override and switch

gears. Not recommended
