That power-split planetary gearbox is great. They "have CVTs", literally, because it's a transmission and it's continuously variable, but it's not a steel band

That power-split planetary gearbox is great. They "have CVTs", literally, because it's a transmission and it's continuously variable, but it's not a steel band and roller that'll turn into metal shavings. Indeed, a planetary "CVT" is simpler and more reliable than a traditional six-speed automatic. But people get triggered by the word "CVT". We should instead say "steel band" and "planetary gearset" or something.
