Awesome - thanks. I knew that quote sounded familiar. Good reference.

The part it doesn't do as well as I've seen (say, on my wife's Merc) is that it doesn't have a way of bumping the speed up and down by 1mph (or 1kph if you prefer the better units - as an engineer it makes me cringe that our government gave up on switching over when it was cheaper...).
Agreed on the terrible ergonomics, but not all of your other points. And the "forgets below 30" is not correct; the limit, I think, is 2mph or a full stop. Resume works ok above that. Have yours checked. (And override is done with the go pedal.)Ugh. The cruise control in the Roadster is dreadful. I'm a cruise control junkie and use it for ALL my driving in ALL my cars. The 1985 Corvette had the best non-adaptive cruise control ever made. The 2011 BMW 550i has the best adaptive cruise control ever made. (no bias here, I don't own either car).
The Roadster is horrible. Terrible ergonomics, stupid 30mph lower limit, forgets the "set speed" if the vehicle speed drops below 30mph, cancelling will throw you through the windshield, trying to overridge during passing is less than graceful, dropping back to the desired speed after passing is less than graceful, etc. I'd rate it a D-.
Did I mention "terrible ergonomics"? I better mention again just in case. Terrible ergonomics.
I just hope that it was some Lotus part and that the Model S will be much better.
Vauxhall is a UK-only brand for GM - the same cars are generally sold as Opel in the rest of Europe.What's the story there? It seems backwards that a British maker would source a crappy GM part, but I guess I shouldn't be surprised.

Ooo, do it! ... then send photos. I wish I knew more about the Elise so I could help with the research (assuming that there are easy-fit options that could be moved over from Elise to Roadster).Oh, and another thing; the prototype cars used the GM window switches; the early round ones; I loved those in the Cavaliers and Carltons, they had such a lovely 'click' when you pressed them, and they lit up. Stupid really but before the car shipped, in my mind I imagined clicking them; part of the whole experience. Crazy eh? Ooh, I wonder if I could retro-fit them...
I might be way off here, but I don't think that any cruise control system ever touches the brakes. At the most, you'll get engine compression braking (ICE) or regenerative braking (EV).My acura very easily keeps the exact speed, even down a steep hill. It will even downshift instead of riding the brakes all the way down.
In the late 80's I built my own fuel injected engine for my drag car, and also built my own fuel injection car computer and programmed my own cruise control software (all in 6502 machine language no less)...
Ha! In the late 80s I built my own digital dashboard / car computer based on a Vic20 motherboard all in 6502 (6510) assembly as well!
But I think you got me beat on the fuel injection part. I didn't try to touch the actual drive-train interface... Just lighting and monitoring.

My comments were for Roadster 1.5. Anyone else with 2.0+ that have experienced the "forgets below 30" issue ?

My version 2.5 has this same behavior....
What I'm saying is that my 2010 Roadster will forget the set speed if the vehicle speed drops below 30mph.
forgets the "set speed" if the vehicle speed drops below 30mph
Resuming a set speed
Press R to accelerate to the previously set speed. This function will not operate if the previously set speed is zero or if cruise control is already operating.
The set speed is reset to zero when:
1. The starter switch is turned to the OFF position.
2. Reverse gear is selected.
3. The hand brake is applied.
4. The vehicle speed is below 1.6 km/h (1 mph).
