While this 'always done it this way' thinking might apply to some people, I don't feel this applies to me at all. I'm constantly pushing the envelope, and people who know me have said that I'm a bigger, better, faster kind of guy. But safety IMHO is important.
It's ok to improve something, great in-fact! My house is full of gagets. But not ok to make it unsafe in the process of improving things.
And so yes, I would very much like a switch that allows me to dumb down the cruse control to get rid of the sudden unexpected breaking, until it's working better.
For example, it's sort of like the switch that browsers (Firefox, IE, Safari, etc.) had (and most still have) to allow javascript to be turned off if there appeared a dangerous problem. Today we all trust javascript more. But in it's early years it needed an off switch just to make sure it was safe from unexpected sudden craziness.
