I rented a car last July, and I specifically picked out a small one because I wouldn't need to carry any cargo or passengers around.

As soon as I drove off the lot, 3 warning indicator lamps lit up, including "Tire Pressure" so I stopped at a service station, thought for a moment, then drove back to the rental lot.

The other indicator had something to do with crash protection, and I think we worked out how to disable the system. After putting air into my tires, I was good to go.

So I'm thankful that those lamps indicated some actual conditions. I always kind of make a point of taking out the Owner's Manual and leafing through it, however briefly, just to see that it covers everything. They're still fairly comprehensive. I really appreciate that.

Any alarm that causes to take the correct action is good. However if it causes you to take the wrong action it is bad. If the engine lost all oil but you choose to fill the tires because that is the alarm you choose to pay attention to that is bad. Normally engines don't lose oil and so going to fill the low tire is the right call. (If the tire is very low stop now is the right answer)
