You have been voted down but what they have failed to add is the following -

Mcdonalds have not changed the temperature of their coffee and the legal precedence has not been replicated. Probably because hot coffee causes injuries when spilled and the case was, as McDonalds maintain, a legal fluke. She got lucky.

In McMahon v. Bunn Matic Corporation (1998), Seventh Circuit Court of Appeals Judge Frank Easterbrook wrote a unanimous opinion affirming dismissal of a similar lawsuit against coffeemaker manufacturer Bunn-O-Matic, finding that 179 °F (82 °C) hot coffee was not "unreasonably dangerous".[21]

In Bogle v. McDonald’s Restaurants Ltd. (2002), a similar lawsuit in England failed when the court rejected the claim that McDonald's could have avoided injury by serving coffee at a lower temperature.[22]

Since Liebeck, major vendors of coffee, including Chick-Fil-A,[23] Starbucks, Dunkin' Donuts, Wendy's, Burger King,[24] hospitals,[25] and McDonald's [26] have been defendants in similar lawsuits over coffee-related burns. The courts in these lawsuits did not find hot coffee unreasonably dangerous or defectively manufactured.

Judge Easterbrook: "The smell (and therefore the taste) of coffee depends heavily on the oils containing aromatic compounds that are dissolved out of the beans during the brewing process. Brewing temperature should be close to 200 °F [93 °C] to dissolve them effectively, but without causing the premature breakdown of these delicate molecules. Coffee smells and tastes best when these aromatic compounds evaporate from the surface of the coffee as it is being drunk. Compounds vital to flavor have boiling points in the range of 150–160 °F [66–71 °C], and the beverage therefore tastes best when it is this hot and the aromatics vaporize as it is being drunk. For coffee to be 150 °F when imbibed, it must be hotter in the pot. Pouring a liquid increases its surface area and cools it; more heat is lost by contact with the cooler container; if the consumer adds cream and sugar (plus a metal spoon to stir them) the liquid's temperature falls again. If the consumer carries the container out for later consumption, the beverage cools still further."

McMahon v. Bunn Matic Corporation, 150 F.3d 651 (7th Cir. 1997)

Judge Field of the Queen's Bench wrote: "If this submission be right, McDonald's should not have served drinks at any temperature which would have caused a bad scalding injury. The evidence is that tea or coffee served at a temperature of 65 °C [149 °F] will cause a deep thickness burn if it is in contact with the skin for just two seconds. Thus, if McDonald’s were going to avoid the risk of injury by a deep thickness burn they would have had to have served tea and coffee at between 55 °C and 60 °C. [131–140 °F] But tea ought to be brewed with boiling water if it is to give its best flavour and coffee ought to be brewed at between 85 °C and 95 °C. [185–203 °F] Further, people generally like to allow a hot drink to cool to the temperature they prefer. Accordingly, I have no doubt that tea and coffee served at between 55 °C and 60 °C would not have been acceptable to McDonald's customers. Indeed, on the evidence, I find that the public want to be able to buy tea and coffee served hot, that is to say at a temperature of at least 65 °C, even though they know (as I think they must be taken to do for the purposes of answering issues (1) and (2)) that there is a risk of a scalding injury if the drink is spilled."
