I would say that it is poor practice to stop, at a junction or lights etc., in gear with foot brake. I would suggest that, unless you expect to be held up only momentarily, when you roll to a stop you should apply hand brake and shift into neutral. This will reduce wear on gears, clutch ( as it drags and heats up etc), fuel ( as the dragging clutch causes engine to call for more fuel to keeps revs 'up' ) and stress to normal hydraulic brake system. Also not blinding people behind you with all them 21 Watt brake lights illuminated ( I know they are LED's, but are equivalent to 21Watt ). By the way it is probably wise to 'nip up' your hand brake adjustment so that is capable of holding the Jazz in first gear at tick over speed on first or second notch / click. Remove your centre console around your hand brake, jack up a rear wheel and with a 10 spanner do up the slack until the wheel just starts to bind. Then swap the jack to other rear wheel to compare. maybe take for a little test before you put the console back. Tools are 8mm socket ( cross head if your strong enough for rea cup holder hidden screw ), medium blade screwdriver, trim tool ( to remove trim under hand brake lever ) and 10mm spanner.
The car can pull off with hand brake on.
I have had a Jazz EX (1.4) I-shift for 1 week now and am liking the semi automatic. I have giving it new filters and engine and gearbox oil ( MTF 3). Sweet as a nut! As they say.
Just my opinion about waiting in Neutral with handbrake on ( similar to normal motorbikes with sequential gears and clutch ) I hope I don't offend with my tips. If you are not moving put it in Neutral!
