Are you really that ignorant? This requirement will not add cost or weight to the car. From the car and driver article (Dec '09) linked above:
"Since the advent of electronic throttle control, many automakers have added software to program the throttle to close—and therefore cut power—when the brakes are applied. Cars from BMW, Chrysler, Nissan/Infiniti, Porsche, and Volkswagen/Audi have this feature, and that’s precisely why the G37 aced this test."
So, aready being done by a wide range of companies, it is only a small change to the software they already have, and it allows a very logical override: if you press the brakes then the throttle will close.
The whole excuse of "when I was little we didn't have all these regulations" is total BS. I especially love the "we didn't were seat belts or have car seats, and look I survived." No shit, if you were in a high speed accident, you would have dead or had serious injuries and likely would not be here to say that crap. Does everyone get into that type of accident? - No, but enough, and the injuries are so severe that prevention is the best option.
Previously, AT&T slowed speeds for subscribers who reached the top 5% of data users for that billing cycle and geographic location. Customers were outraged, arguing that the percentage method meant they had no way to know what the limit was — until AT&T informed them via text message that they were in danger of exceeding it.' AT&T still maintains the position that less than 5% of its users exceed the 3GB threshold each month.
So if they limit the top 5% of data users for that billing cycle/location, but less than 5% exceed 3GB, then the point where they limit users has to be less than 3GB in most locations.
And how is it done for "that billing cycle". After the first day (hour, etc.) of the billing cycle, did they throttle the top 5%? Once you were throttle, did you stay throttled until the end, even if you were no longer in the top 5%?
I can't imagine anyone thought top 5% would be a good idea. I'm wondering if they did that to get everyone really upset about it, then fall back to this more "reasonable" solution, to look good. Instead of starting with the 5GB limit, and having a lot of people complain about it.
So your argument about 'just' getting a ticket does not hold.
Beware of the Turing Tar-pit in which everything is possible but nothing of interest is easy.
