How would shifting gears be fun w/o the clutch?
tiptronic, steptronic...or whatever its called, depending the car maker, has been around for decades.
Even the 1995 Honda Accord base model has it. Just shift it to #1, and change as please.
I used to drive mines around like that for awhile pretending i have some awesome car

I was young back then.
