Same as if I'm driving in winter and hit a patch of ice - Visually, it looks identical to the rest of the snowy, icy roads here, but I will drive if I feel and here that I'm spinning my wheels or sliding sideways.
If I smell coolant, oil, or a belt, even if my eyes tell me my gauges disagree I'll be pulling over for those issues as well.
Conversely, if I've replaced a tire and the TPMS light says the removed tire in the cargo area has low pressure (duh, that's why I changed it) but I know the spare (without a TPMS transmitter installed) is good, or otherwise know that the idiot light is a false positive, I'll trust my other senses over my eyes.
* Screeching breaks from the right
* Sounds of a rattling bicycle trying to undertake you
* An approaching emergency vehicle
* Other cars beeping their horn at you
Of course you will confirm such situations visually, but you definitely using hearing in addition to sight.
