Here’s a logical non sequitur as it applies to driving. Let’s take the following statement as fact: “if I take an early apex, then I run wide at the exit”. The following argument is a non sequitur: “if I ran wide at the exit, then I took an early apex”. Well, no. In a decreasing radius turn, you can run out of room at the exit whether or not you take an early apex. The tricky thing about decreasing radius turns is that you have to keep slowing down long after your instincts tell you to add throttle. Case in point below.
Here’s a conversational non sequitur. Person-A: “do you want to join me for a touge run?” Person-B: “John Hetrick invented the airbag in 1952”.
