Are they useful to an everyday owner? Not really. They were added to most vehicles in the late 80's because they tended to enhance the performance image. Like you really need it in a Focus. Most were added because of the standardization of the electonics that were in dash clusters. Do I use it in my Corvette? Sure when I am ringing it out down a country road. I want to make sure I shift before the red line. Like the speed limiter would let me anyhow. If you pay attention to the dash gauges at all you probably would notice that engine speed changes as the gear ratios are changed. If you are going down the road and you notice that the engine is running fast just glance at the tach to check engine speed. About that time you notice you just bumped the selector into nuetral as you were texting or applying eye makeup.
Since 99% of the people out there don't understand the difference between torque and horsepower they find it mostly useless. When towing big loads in non-flat terrain it is indispensable when matching gears to road speed. This naturally carries over when you get out of the truck and get into the car.
