On the face of it, it may sound like a frivolous law suit but if you look into the details, it was far from it.

Coffee served by McD (180 to 190 degrees Fahrenheit) will give a person third-degree burns in two to seven seconds, while home-coffee brewers normally serve coffee at much lower temperatures (130 two 140 degrees) which won't immediately burn you. Yes, Starbucks and other joints do serve coffee at the hotter temperatures -- because some customers prefer it -- but then again, they get sued for it also.
Also, she attempted to settle for $20,000 at one point, and McDonald's refused
You may have heard that she got millions of dollars, when the final award was $640,000. Then from that you take out the medical bills (hint: skin grafts aren't cheap).
But she has to take some responsibility, right? She may not have been driving, but she was trying to open the lid in her lap so she could add cream and sugar. That's kind of careless, isn't it? Why couldn't the jury see that?
Well, they did. That's why the compensatory damages portion ($200,000) was reduced by 20 percent, because they ruled it was 20 percent her fault.
That's not to say the seller is faultless - but the verdict still strikes me as entirely disproportionate. Then again, that's the norm nowadays, isn't it?
I understand people get stuck on the 'coffee' aspect, but many acids cause similar levels of tissue damage. There is a huge difference between water at 140f and 190f.
To put things in perspective an autoclave at 134 °C for three minutes is as effective as 121 °C for 15 minutes. Steam at 134 °C can achieve in three minutes the same sterility that hot air at 160 °C can take two hours to achieve. Granted, 249.8F = 121 C, but water can transfer a lot of heat vary quickly.
You mention the amount of time needed for serious burns to occur, yet that amount of time is huge compared to the time needed for water (or coffee) will flow away off or for people will to react. For her to remain exposed to the full load of coffee for around 12-15 seconds requires a pretty odd set of circumstances. For those burns to be large enough to be life-threatening normally requires a large surface area to be burnt, and that requires a large amount of coffee for a long time. (The 12-15 number is from wikipedia which says her lawyers produced evidence that this is the duration t 82 degrees celsius that "may produce third-degree burns").
Of course, there's the complicating factor here that she was quite old; at 79 she would not have been as resilient as younger person. And while that's a terrible shame, it's unreasonable to blame macdonalds for aging. Reading, she weighed just 47kg before her injury, which is low. I don't believe that a healthy person would have sustained her injuries.
It sounds implausible that she could have managed to sustain those kind of injuries given the circumstances - unless some other factors played a role (such as frailty due to aging). It's terrible she suffered as she did, but I still don't see how that could have been reasonably foreseen by macdonalds (and therefore the verdict seems unreasonable).
The point of the lawsuit isn't (just) about what happened to her, but critically also about the degree to which MacDonalds' was taking unreasonable risks. And as wikipedia points out, there have been many, many similar lawsuits, that apparently were not successful. (And note that coffee is still served at that temperature).
As to water vs steam, steam has effectively a much higher heat capacity but far lower density. 90c water can cause 3rd degree burns in as little as 2 seconds but clothing generally extends the exposure duration significantly.
PS: In the end it was a low cost lawsuit which was settled for presumably less than 600k and well within the cost of doing business. They changed cup design not temperature, but that's about it. As far as their concerned the issue was not the actual cost but discouraging people from suing in the future as it's been 20 years without a repeat.
Well, that's a reasonable point. Children and old people do have more fragile skin and are going to suffer more severe scalds because of this.
She didn't just have any old minor burn; hers was huge - she stayed for months in the hospital and lost 20% of her body mass; that's not your typical scalding accident.
Such lawsuits have been repeated, they just haven't been so successful. The fact that it's been 20 years merely underlines how unusual her circumstances were - and perhaps how bad that original cup design was.
I just think that we rationalized the risks to our safety because a company as large as McDonald's must have done a lot of studies on their coffee and figured out a temperature that was the perfect compromise between preventing disease and putting meltdown hot liquids in the hands of people driving cars. I thought that their goal in making the coffee that hot was to lower their net liability (and hence, the public's net danger) rather than what it really was - a way to serve coffee that got very old.
It was a business decision that had a money value for the company. They undertook it in order to make money. Paying for the externalities in court is a good place for McDonald's to learn how to recalibrate how much injury is worth, and see if their price calculation for raising the temperature of their coffee still makes sense.
At the time, the reactionary corporate rhetoric parodied the position of consumer advocates as requiring businesses to cover coffee cups with long elaborate disclaimers about how coffee could possibly be hot. Go buy a cup of coffee at McDonald's today - you'll see nothing of the sort. Turns out you don't need much if you just don't serve coffee as hot as lava to save money.
Try making a coffee today and taking the temperature of that coffee ten minutes after making it. I doubt it'd be hot enough to cause full thickness burns.
Also, if you put a lid on coffee (which you'd do when you want it to stay warm as when it's not necessarily for immediate consumption), it can stay hot quite a while.
Personally, I don't believe most people would have gotten third degree burns in a similar situation. Unfortunately, she was old (79), light (therefore likely frail; 47kg), and wore cotton (absorbent) sweatpants, and she must have kept them on for at least 12 seconds according to the evidence her own lawyers presented. Frankly, that's just a bunch of bad luck piled up. Most people would have stood up when the coffee spilled toward them, not sat in it for that long, and most people would have taken off at least partially the hot pants, thereby distributing the heat better, some people probably would have their pants off entirely by that point. (Wikipedia claims scalding rarely results in third-degree burns, let alone third degree burns on 6% of your body's surface area with a lot more second degree burn area).
Even at boiling point you need a number of circumstances to get this kind of injury. It takes quite a while, and needs to affect a large surface area, and needs to somehow be retained near the skin. That's just not all that likely to happen; and when it does, being old and light make recovery slower and less likely. She simply had the worst circumstances on all fronts.

2% of non-fatal household scald injuries in > 65 year olds needed tranfer to specialist hospitals for specialist treatment. If that's what you mean by rare then I guess we agree, but it's not what I'd call rare.

The CDC used to have tables for the length of time it took to achieve partial thickness or full thickness burns at various water temperatures.
At just 60 C it takes only five seconds to get a serious scald. At the temperature of 80 C burns are almost instant and probably require surgery.
Here's a nice chart with plenty of sourcing so we can check it for accuracy.

> at 180–190 °F (82–88 °C) McDonald's coffee was defective
Specifically, the hot-coffee lawsuit for McD was IMHO a genuine lawsuit that only gets bandied about because it 'sounds frivolous'. The plaintiff sued because McD was significantly overheating the coffee to reduce costs, much more than expected, and all Liebeck was looking for was to cover her medical expenses for third degree burns. There was the usual - "ignore and be dismissive about the problem" perspective from McD officials that led to heavy punitive damages being awarded by the jury. See more details here: http://en.wikipedia.org/wiki/Liebeck_v._McDonald's_Restauran...
Since Liebeck, McDonald's has not reduced the service temperature of its coffee. McDonald's policy today is to serve coffee between 80–90 °C (176–194 °F),[28] relying on more sternly-worded warnings on cups made of rigid foam to avoid future liability, though it continues to face lawsuits over hot coffee.[28][29] The Specialty Coffee Association supports improved packaging methods rather than lowering the temperature at which coffee is served. The association has successfully aided the defense of subsequent coffee burn cases.[30] Similarly, as of 2004, Starbucks sells coffee at 175–185 °F (79–85 °C), and the executive director of the Specialty Coffee Association of America reported that the standard serving temperature is 160–185 °F (71–85 °C). Retailers today sell coffee as hot or hotter than the coffee that burned Stella Liebeck.
The National Coffee Association also suggest 195-205F.
