I am well aware of this
but the more you are familiar with the car, the less you will ever need to rely on built-in understeer to get you out of a situation. Your description for why the car has smaller front tires looks more like you're reading from a marketing or legal brochure.. it just looks like you're repeating what others, who also have never had the chance to really push their cars in a safe environment so they can learn how to control it, have told you.
Don't take that as me pushing you to do something to lessen any understeer. I wouldn't recommend that you do so until you are confident with the car at high speed and in extreme situations... something you can only really learn in a car control clinic and at the track. But I do believe that once you gain that confidence you'll start to worry less about thinking that oversteer is the way to death with the car
