hogasm,
If I remember correctly, drive-by-wire (throttle control) has been around on cars since the very late '80's. I think BMW had it first, back in '88 or '89. Initially there was no financial benefit, so it only showed up on more expensive vehicles where the cost could be buried more easily. As computers and electronics became smaller, less expensive, and more reliable, these types of controls became available on a broader selection of vehicles. Now we have drive-by-wire braking and steering, in addition to throttle control. One of the vehicles my employer produces even has the ability to sense an impending collision, reduce throttle, and even apply the brakes with no input from the driver.
My issue with all of this on a Harley is twofold. 1.) I enjoy riding bikes because the experience is direct and immediate, unlike the typical modern automobile which has had all the fun (and skill requirements) removed. I know how to apply throttle properly depending on conditions (let's see, how about WOT immediately after starting the bike, or during a rainstorm - duh!), as well as proper braking technique, and would prefer to handle those things myself. 2.) My experience with H-D indicates that they cannot be trusted to properly implement new (to them only, old hat to the rest of the world) technology without screwing it up. Their p-poor EFI implementation damn near got me killed shortly after buying my SEEG; I'm quite sure I don't want to give them another shot at me using drive-by-wire.
