actually i advise drivers to place their a/t cars in P when stopped in traffic - this way hindi aatras o aabante agad even if the car is on a slope, coupled with your foot on the brakes.
problem lang that i can see is that if the car is in D and you're stopping it with the brakes, you'll probably raise the temperature of the a/t fluid.
pag manual lang naman dapat naka neutral pag naka tigil than depressing the clutch. kasi kung naka depress lang, masusunog yung clutch mo against the smooth plate around the pressure plate. also in cable driven clutches, anlaking stress binibigay mo dun sa stuff na stopper ng clutch cable (the one near the transmission) i know from experience because i tore one apart literally, but not because i depress the pedal in traffic
pag hydraulic clutch naman pag nakatapak ka, the clutch fluid heats up , baka lumusot pa yung master cylinder pag tagal.
