That's part of the problem right there. There IS and WAS no problem with the McD's machines. They made coffee hot, very hot. Well, water can only get so hot before it isn't really 'water' anymore. You could steam the coffee and let it recondense, but not sure that would be very time effective.
Coffee is hot. The heat range of the McD's coffee was normal, and the consumer is the biggest flaw in the cup design. Admittedly, McD's could have used a more stiff composition for its cups to make them flex less so the lid wouldn't pop off, but even then it was a minority issue. There were previous occasions of burns, but the same could be said for the clumsy consumer spilling coffee on themselves at home. I know my personal coffee maker would probably scald me just as quickly. Making it fireside, while camping, with boiling water in a pot has the same dangers and effect to produce coffee.
Hot tea can also carry the same dangers. It's all about just being careful. If you are getting a hot beverage and plan on driving while trying to drive or hold it, that is just foolish. Drink it at a red light, pour it into a 2nd more stable cup in the parking lot... save it until you get to your location. McDs deciding not to change the design so long as costs remain low, sounds bad at first thought, but really is common practice and reasonable when doing business. You look at the failure rate and reasons, cost to change the design, and possible benefits of changing the design (among many other points), and then make your decision. A cup is a cup, you can only do so much with the design McD and most other places work with. Cheap styrofoam would be the only weakness in the design. I still feel this whole thing was overblown, and the zealous jury just wanted to try and make an example out of McD. The lady got her money, McD got mocked for a few years like it was going out of style (which it did...), and not its a common reference and argument piece on society and the flaws in our legal system. More often than not, this case is cited as a failure of the legal system, where common sense can be litigated.
