I think of it this way. Most cars produced didnt' get all the bells that we did.

Most didn't get an idiot light for oil pressure and ours is pretty worthless at 5psi or less.
Most didn't get an oil level sensor, and ours is pretty worthless since very few of us ever see that light come on.
Most didn't get a coolant level sensor in the radiator, and that's totally worthless because it gets goopy and gives a bad reading more often than a good one.
