I've never even drove an automatic. Wouldn't want to either
Have you ever driven a vehicle with a really hard clutch? I've been in cars built for the drag strip, extremely tough clutches. Then when you get into the cab of a 18-wheeler, that clutch is enough to make your leg snap off- now imagine trying to use it a day or two after working legs!
It's nice to drive a clutch and mess around in. But if you do it in a rig all day, sometimes it's nice to just be able to put the shifter in drive and go.
