Do you own and / or operate an automobile? if so, does it have a carbeurator, points, rotor, and condenser?
If not, did you know all that stuff is now accomplished by electronic fuel injection and a computer, with feedback input to the emissions control sensors?
If you were to rent an identcal brand, model, and model year vehicle, would you expect it to operate significantly differently?
Good point. Actually, I prefer cars with cabs and alternators. I went as far as to own a Caterham Super7 (hence my handle name; left my garage for practical reasons after a short while).
Presently, I have two cars at my disposal, and the one I drive daily is a JDM Subaru Impreza (WRX-RA STi Spec C) that's spitting out approximately 350HP and doing 0-100kph in roughly 4secs, thanks to a modified
COMPUTER that controls everything from fuel injection to cam phase to spark timing. It also features an
ELECTRONICALLY controlled center differential called "DCCD". But then, I do have a twin plate carbon clutch at my foot that will disconnect via pedal operation, and the transmission itself is also manual/mechanical. As for the brakes, they do have boosters, but I have also stopped the car without the vacuum, when the engine stalled while running around corners on a track day. I did try the Nissan GT-R and Lancer Evo X, both with twin clutch automatic transmissions. They were faster around the track, but felt bland compared to cars with manual transmission. So, for me, cars will always have three pedals and a knob.
As for renting an identical vehicle, impossible. But whenever possible, I would rent a car with manual transmission over an automatic transmissioned car with better features.
Maybe you weren't satisfied with my explanation for why I dive two identical computers in different modes? I did have one Stinger die on me while diving once. It went blank and after turning back on, locked up as if I had made a deco stop violation. Quite puzzling since I was diving well within the NDL. This got me wondering whether two might hang simultaneously.
And as for PCs, the Macintosh Plus I was using to write reports back in collage pulled all kinds of pranks on me. System hanging after 20hrs of writing demolishing most of the report, capacitor in the Jasmine HDD's power supply board burning up while writing another report, etc.
If you still aren't satisfied, "I do it because I want to"
