Poorly explained, sorry. I meant in the first case, the 10mpg car is using 10gal to go 100mi. So you can save, at best, 10 gal. In the second case, you are only ever using 3 gals, so no matter how much you improved that car, you could only save 3 gals. Thus there are seriously diminshing savings returns in increasing the mpg measure.

The point is that the number of miles driven is assumed fixed. Say you drive 100 miles, then in the first case you could potentially save 10 gallons. In the second case, you can save at most 3 gallons.

So you didn't read the article. there is a whole section entitled "The Myth of Multitaking" quoting research that shows your argument to be total shit.

Yeah, they probably write things like "usage of the language" rather than "use of the language." Terrible.

The wrong type of vehicle thing is a red herring. Police often get things like that wrong and if you could dismiss a case on a little mistakes like that, it would be unreasonably hard for the police to do their job.

But 1 is not a prime number

I dont think that BP can unilaterally raise the price of gas given that some competition exists.

There are sleeping bags that are -60 rated so you'd be fine. My point was that there while are loads of reasons not to get an electric car, fear of dying of the cold is not a very good one.

Or keep a warm sleeping bag in your car for such eventualities.

I trust Google infinitely more than I trust Microsoft.

So what exactly do you think Microsoft is going to do that Google won't?

The leaseholder of the well has a legal responsibility to clean up any mess emanating from the well. Legally, it is BPs fuck up. Morally, it is their fuck up because they hired the company and were in a position to specify what safety measures should be taken. An argument like yours would mean that a large company basically never had to take responsibility for anything just by subcontracting stuff out.

We are talking about 64 bit integers. Matlab has 64 bit floating point arithmetic. This means you can do exact integer arithmetic up to 2^53. I'd say mathworks has a pretty good idea of the demand for 64 bit integers and it is not that great -- it's not like it is a huge job for them to implement it so they would surely do it if their customers wanted it.
