> Liebeck's attorneys argued that coffee should never be served hotter than 140 °F (60 °C), and that a number of other establishments served coffee at a substantially lower temperature than McDonald's. The attorneys presented evidence that coffee they had tested all over the city was served at a temperature at least 20 °F (11 °C) lower than McDonald's coffee.
Reading through wikipedia's discussion of the trial and verdict, it sounds like the case hinged entirely on the temperature of the coffee being unusually high, and not the cup design.

And no, there is no coffee professional (organization, individual, whatever) brewing coffee at 140*F.
Additionally - 140*F water is still going to burn if you spill it all over your clothing. Lastly, the customer removed the lid of the coffee while between her legs, which is how the cup was crushed and coffee ran all over her.
The case was absurd...
I don't understand how what you wrote gels with the grandparents comment of:
> Lastly, the customer removed the lid of the coffee while between her legs, which is how the cup was crushed and coffee ran all over her.
> Since Liebeck, McDonald's has not reduced the service temperature of its coffee. McDonald's current policy is to serve coffee at 176–194 °F (80–90 °C) [...] 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).[citation needed]
Any of this coffee can give you life changing injuries. That's why it is important that it be served in sturdy cups with safety warnings.
Which is probably too hot. See "A Review of Hot Beverage Temperatures—Satisfying Consumer Preference and Safety":

You don't chug your coffee on your way from the counter. You probably have some other items that you consume before you even start sipping on the coffee.
If someone serves me coffee at the perfect consumption temperature I'm going to be annoyed that it is way too cold and it is for sure going to be disgustingly cold at the time I actually consume it.
The correct temperature is supposed to be way too warm for consumption. Then you can sip at it while it is still too warm to drink comfortably while you "wait" until it is at your preferred consumption temperature (which varies wildly due to personal preference).
The same article says McDonald's own research showed the opposite.
> McDonald's claimed that the reason for serving such hot coffee in its drive-through windows was that those who purchased the coffee typically were commuters who wanted to drive a distance with the coffee; the high initial temperature would keep the coffee hot during the trip.[12] However, it came to light that McDonald's had carried out research finding that customers intend to consume the coffee immediately while driving.[22]
Further, I'm guessing but doubt that commuters wouldn't go to mcd just for coffee, whatever breakfast(?) maybe didn't last long enough for it to cool down. Sure, but that all depends.
And apparently, commuters didn't mind enough to find something else.
Part from safety issues I haven't really seen any convincing argument against "too hot" coffee.
And come to think of it, you won't buy a coffee (at a drive-through!) when you are one minute away from your destination.
You most certainly have time to let it cool down and enjoy it at your preferred temperature. Even if you intend to consume it as soon as possible.
See Table 5, which includes "After dilution or cooling".
Why would anyone think it is OK to serve a drink so hot that it can cause severe burns?

And it doesn’t make the grossness of the accident into prima facia evidence of the culpability of any one party up the line, as it’s always presented in these discussions.
"Black and oolong teas are generally steeped in hot or boiling water (about 210º F) and brewed for about 4-5 minutes. Green tea is steeped at a slightly lower temperature 180º F from 4-15 minutes. The longer tea steeps, the stronger the flavor with bitter notes."
And I don't think anyone recommends you put hot beverages in your crotch area.
It also seems clear to me that one should take into account that someone is having the drink in the car and not at the table if you’re operating a drive-through restaurant.
Additionally - the detail often left out of all the armchair analysis is the customer placed the fresh cup of coffee between her legs while in her car, and removed the lid. Her legs crushed the now-unstable cup... and she was unsurprisingly burned.
Any temperature above 100*F is going to burn. There is no safe temperature above 100*F that is not going to cause 2nd and 3rd degree burns.
So much lawyers' propaganda. We are engineers here. We are aware that coffee is water that boils at 100 degrees centigrade and gets no hotter than that. Every damn idiot and those more intelligent know full well that writing "Caution: contents hot" in microscopic text does absolutely nothing to make recently boiled water more safe.
Sure we should all feel sorry for someone who is badly burnt. Absolutely we should. It is inhuman not to feel so. And who can fee sorry for a corporation? Nobody should.
And we've let the lawyers use that sympathy to run riot writing themselves cheques on society's labor. As engineers we look at it and cry "Tort reform now!" and it is further and further away? Is it what killed Carter's presidency? Dunno. Last time it was anywhere near having anything done and that was 4 decades ago?
But go ahead and keep repeating it like the water was super heated to a 1000 degrees and writing text on the foam cup stops anyone from being burnt by boiled water.
Or don't. Really, just don't. Just because something sounds insane doesn't mean to say it actually isn't.
"Caution contents hot" Does not seem to be any way an engineering fix for this though, does it? Like seriously, why do you think that is written there? People expect cold? That fixes it? The mind boggles. So many legal fees on garbage like this.
But yeah, the lawyers got everyone jumping to their BS and so the zeitgeist will go into wikipedia.
Caution: contents silly.
Having "caution hot" was probably not enough of a warning. They should have put "caution burn risk" or something like that on the cups.
A purchaser has no right to blame anyone else for putting a freshly brewed cup of coffee between their legs while driving a car. That is dangerous and reckless driving and they should be charged for not taking the proper regard for others safety.
You can hate mcdonalds and I /really/ do and see this BS for what it is. Exploiting your sympathy for a burn victim to accrue a mass of lawyers fees. This case and all the other legal actions on the same principle.
You don't have to be a "rugged individualist championing personal responsibility above all things" (aka libtard) to see it. You can even be a a massive socialist and still see the incredible damage to ordinary people engendered by this frankly insane interpretation and enforcement of the law. Nobody is safer, but the existing lawyers get richer and their highly productive segment of the economy grows. The effect on insurance premiums across the entire economy has been profound and immense.
Add up all the legal fees and flow on then compare to "caution: contents hot" written in tiny print on a cup that cannot be seen without holding said cup. Include all the additional legal fees from just this kind of nonsense for any small business trying to grow that come out of this. That is the outcome.
It's such an idiotic "AKHTUALLY it's not what it seems."
AKHTUHALLY it's not crazy like it sounds because it's really good for lawyers who have a huge interest in avoiding the necessary legal reforms and have done a truly stellar job pursuing those interests.
An engineer should know that the temperatures being used in this context are in Fahrenheit, and that on the Fahrenheit scale the boiling point of water is 212 degrees...
But go ahead and keep repeating it like the water was super heated to a 1000 degrees and writing text on the foam cup stops anyone from being burnt by boiled water.
McDonald's knew that the design of the cup and lid were defective, given that they had received several hundred reports of burned customers prior to the woman in the Hot Coffee lawsuit.
The "Hot Coffee" moniker is actually propaganda from far-right Koch-funded tort "reformers" who have spent tens of millions to convince people that this case was about just about someone spilling hot coffee (it was not) instead of a poorly designed product being kept in the market despite the business knowing of its flaws and choosing not to fix them (like the Ford Pinto).
Writing "Caution: contents hot" in tiny writing that cannot be seen until after the cup is picked up is not a safety improvement so no admission there.
I can hold two things in my head at once. I can be desperately sorry that a lady spilled coffee down her crotch and got burned and have a great deal of sympathy for her, I could have done something as idiotic as that, easy. There but for the grace of $deity go I. At the same time I can think that really isn't anyone else's fault that she put a cup of takeaway coffee between her legs driving a car. Making decisions as poorly as that should preclude you from having a license. A rigid cup could have had the same result and while in agonizing pain she could easily have run down children.
Writing "caution: contents hot" in tiny writing is just flipping daft and deserves to be scorned for the nonsense from awful lawyers that it is.
This idiotic thing that looks idiotic because it is gets the AKTUHALLY treatment to defend lawyers and stop tort reform. Bleh. Oh, btw, I hate mcdonalds.
