LMAO, tell me you have no fucking clue what you're talking about without saying it. And I'm going to tell you exactly why you're a fucking moron:
It replaces a cable with an overly complex potentiometer with circuit board and wiring
- A potentiometer is one of the simplest electronic components, nothing more than a carbon strip with terminals on each end and a wiper in the middle. Every EFI vehicle with a cable-operated throttle uses this in the throttle position sensor, or TPS. Those fail more often than electronic throttles.
- An electronic throttle body doesn't use any sort of potentiometer, rather a far more precise component called a stepper motor. A stepper motor is little more than a geared-down servo (y'know, like what RC cars use), but with an extra bit inside called an encoder. That encoder is what feeds the throttle position back to the ECU. It also allows the ECU to command the throttle at specific positions based on engine load, for such things like cruise control.
Right off the bat, an electronic throttle has already superceded the oft-worn throttle cable linkage, throttle position sensor, idle air controller, and overly expensive cruise control modules.
that will fail and be irreplaceable 10 Years after the vehicle is Sold, rendering it unuseable.
My guy, you know what a JUNKYARD is? Car-part.com? Fucking christ dude, go outside sometime.
Every “improvement” on cars has been war on removing your ability to fix anything yourself or keep a car for life.
I don't necessarily disagree with this, but you're looking at it from the wrong angle. The existence of an electronic throttle body isn't your enemy. At this point, they have proven several times over to be far more reliable than the mechanical equivalent: cable actuated throttle + TPS + IAC + cruise control module.
Its all throwaway trash now made to stick you on a lifelong subscription while recording your every move (now with cameras inside too yay)
Newer stuff, sure. After that tech has already matured. But the main reason for electronic throttle bodies was actually for emissions compliance. Snapping the throttle closed after a hard acceleration event causes a spike in emissions output. An electronic throttle body essentially eliminates that, while still giving you pretty much the same experience.
Remember, “safety” and “protect the children” is how they take all your freedoms away. And it works because people are stupid.
That's a different problem. Seatbelts, airbags, safety glass, crumple zones, etc. have all been tested and studied extensively. Injuries have gone up with every safety advancement because those who would have been killed before are now able to walk away with scratches or bruises.
