Why? Unless you think it looks kool shifting up and down like youre a race driver around your quiet neighborhood
Automatics are better and safer as you can just concentrate on driving and not forgetting using your turn signal when changing lanes
Manual transmissions are far more reliable, less prone to breaking down in regular driving and sport driving, don't require anywhere near as much maintenance, shift faster in most cases, have better gas mileage in most cases (though this is eroding quickly at this point), don't require a computer interface, don't require programming to shift properly, shift as hard or soft as you like, feel better, and actually require skill.
I feel sorry for the plebes who don't know how to drive them.
Sure, if you actually believe this shit in 2018. ---
