i think they are designed for those people who does not know how to drive a manual car. i had owned a 01 acura cl type s with auto manual shifting .but i would say it sucks cause it is definitely not like manual car. the manual up and down shifting sucks, cause it hesitates and it does not responsible immediately, i would say 0.2~0.3 second delay. but technology might have changed now. on gtr and new lan evo. it might be different. but i would still buy a true manual tranny car with clutch instead of auto with manual shifting tranny.unless it is a ferrari or porsche.
