Got it, hope that helped! I'd be very interested to see what the analysis is for a bike and what the optimal human efficiency is like. In my experience riding road/hybrid bikes vs. mountain bikes, the lower resistance tires reduce

Agreed - you can't really do much without variables/primitives first. Which are might be conceptually harder to grasp

With web programming, a lot of the initial hassle and set up is gone, and visual learning/iteration by hitting refresh is very easy. So I would say, almost as young as they can play around with a web browser, and type on a computer.

Got it - I think you're asking why the peak is still so low at 40mph, and why we haven't shifted it toward 55, or 65. The reason there is a peak at all and we aren't most efficient at 5mph is due to (1) for gasoline cars, l

Good catch! Knew I was missing something when the other comment referenced a quadratic relationship. (Updated)

Longer gearing will improve the high-end efficiency where it wasn't yet optimal - to help 90MPH you could target that with your super 7th gear at "ideal" torque/RPM. However the overwhelming aerodynamic drag means the pe

The thing is we have a lot a lot of leverage on the technological side. Choosing a behavioral and societal change vs. technological is always a trade off - but for this case some things make improving the technology much easier. The median

Right now local transit in the US is often less energy efficient per passenger-mile than a solo-driven Prius or Insight, or even the average-loaded (gasoline) passenger car. The numbers vary of course based on passenger load and route effic

OK, now I understand where you're coming from. The physical limit is that at higher speed, we must expend more energy per unit of distance, to overcome drag (relatively little is lost in braking or rolling resistance of tires.) [1] So

It's not always the most efficient for every car, but there are lots of charts showing this tradeoff. Some cars are more efficient at 65 or 70 than 55 (97 Celica), but in modern gas cars, 40-50mph is where you hit a peak, and you star

In a way, it also helps turnover of tables - it's a soft way of ensuring new customers can get seats and the people who got there first don't stay all day (short of an explicit X hour limit)

Great points, especially on the loans. I'd like to add that you don't need REG 262 except in special circumstances, such as if the seller doesn't have the current title, or with loans (maybe that was part of the context thoug

In California it's even easier than getting a notary - you just need signatures on the title ("pink slip"), and then both parties can fill an online form for transfer or liability. The buyer then goes and hands over the title

Great service! A lot of people don't have experience or simply don't want to deal with the Craigslist experience. Putting another option between a private party sale and the dealer is great. Questions that immediately come to mind

What I really want to know is, if the conspiracy about Yelp taking down reviews based on whether you pay for its premium services. I imagine this is most of the fight with FTC complaints. I've seen so many accusations, but no actual pr

If Canada is like the U.S., the median traffic speed on those roads you mentioned is greater than the speed limit. Thus it's really not a minority/extremely "can't say" opinion you're espousing, but you're

It goes beyond learning though - I'd say we actually need those changed circumstances and advanced technologies for those changes to happen. Trying to adapt a 2010 US morality or system of government to a 1200 Mongols environment or a

The example they used basically paints taking more risk as 'cooler, more rational option' which seems a bit odd to me. Humans are well known not to have a linear utility function for a lot of things (loss aversion) because doing s

It's also a matter of scheduled maintenance: If you buy a car right before a bunch of critical components are replaced, expect a repair bill of $500-1K at the appropriate time. Although a lot of cars at say 60,100 miles will probably n

For people already with a car, the variable costs of driving (maintenance, fuel, etc.) is usually 25-45 cents (lower end is a economy car getting 30mpg city, higher end is a less fuel-efficient, less reliable car). Using 35c/mile, and

Not really the case when you consider the huge rural population of the past and that the 20th century saw huge amounts of urbanization in the US (where 'urbanization' = developed areas and includes suburbs). The lower-density subu

I don't really get the "obtaining their primary residence through Airbnb for extended periods" line - does this mean living at Airbnbs with no other permanent address is breaking a NY law?
