In her defense (or to my embarrassment), I can see it with modern suspensions and modern tires that have such strong sidewalls that you can drive them blissfully unaware. I ruined a Boxster tire once because it picked up a nail and I had no clue (rear), the car felt 100% normal and I was doing freeway speeds - no issue at all, rock stable. By the time someone flagged me over it was ruined and the goop was useless because the sidewall was so damaged. On the flip side, I had a quick deflation on a michelin Super sport (front) and I could tell immediately, that thing is made of bubble gum. It can happen on a modern car... conversely, if I drive my early 912 I can tell you if any corner is 2 psi low ;-)
