If McDonalds was consistently and intentionally making the coffee too hot for consumption, then there's a market solution for that...people would simply stop buying McDonalds coffee. If I go to Starbucks, buy a coffee and then immediately pour it on my lap (and let's assume that I'm not wearing much clothing), it will do some damage. Could easily cause 3rd degree burns. The solution: be careful and don't pour coffee on yourself. If the cashier accidently spilled coffee on a customer, then ok, totally different story and in that case McDonalds would be liable. When you assign blame to manufacturers due to people using products incorrectly, it just increases the cost of the product. The left, is currently trying to do this in some states by holding gun manufacturers liable for how people (not necessarily even people who bought the gun) use the product. Ultimately their goal is to drive up the cost of guns by driving manufactures out of business or at least drive up the cost of guns. I agree with you on the frivolous lawsuit comment.
You're actually lucky or don't drive much if you only see a person blocking the left lane a few times a year. In Portland, Oregon, I see it all the time. But then again, considering the policies that the voters here support, that's not surprising.
You're basically arguing for determinism. How far are you willing to take that argument? So if we were German employees during the 1940s, would we be operating the ovens and organizing people into camps? How one acts depends highly on his/her belief and value system. 2000 years ago, we would not be the same people that we are today including our beliefs on morality. If we're talking sometime before the time of Christ, I certainly would not have been a Christian. But that aside, groups of people behave different than individuals. During the protests of 2020, bad behavior was enabled by the mob. I doubt one person in isolation would attack a cop or loot a Macy's due to fear of consequences or even just reputation as frequently as was happening two summers ago during the BLM riots. But when you can mask up and do it under the cover of a mob, suddenly people feel empowered to do bad things that they would never do alone. I suspect the crowds watching people getting eaten by wild animals example is the same. I doubt a peasant ever went to a Roman guarding a prison and asked to see one of the prisoners eaten by a wild animal. Although the whole premise of feeding criminals to wild animals was done as a deterrent to challenging the ruling power marketed as preserving law and order (same as done in North Korea today). Anyhow regardless of the purpose, it's still the case that you had the masses packing colosseums watching people getting eaten alive for entertainment.
My dad once told me, "The masses of men live lives of quiet desperation".
Isn't that the English way?
His point wasn't just that it's annoying when a slow driver blocks the left lane. His point was that lane rules were designed for safety and efficient flow of traffic. If you don't adhere to them, you not only unnecessarily impede the flow of traffic, but also increase the risk for everyone else on the road (by causing more lane changes and opportunities for collision as well as more instances where cars are traveling very different rates of speed). And it's not just about driving. If people are that careless and lazy when operating a 2+ ton vehicle traveling at 60+ mph...why would they be any more diligent with other less dangerous tasks?
