Just picked up my first automatic/tiptronic car. When I drove a manual, I'd use handbrake and neutral when waiting in traffic or at the lights (unless I was at the head when I'd wait ready in first gear).

What do the assembled PHers do? Put the box into 'Park' or 'Neutral' or leave it in 'Drive with their foot on the brake/handbrake on?

foot brake.

handbrake is an option if you need to be fast on the throttle.

Once in park the handbrake is actually superfluous

Definately handbrake for fast offsky.

Foot hovering over speed pedel, hand on hand brake, thumb on button release, lights change, release handbrake, push go faster pedel with foot, always a winner first away from the lights, assuming of course your in the front.

If I am going to be stopped more than say 10 seconds neutral handbrake. At night especially if raining I tend to do the same but sooner as I don't enjoy being blinded by brake lights. From a mechanical sympathy point of view I've never quite worked out whether it is better to leave in gear or slip into neutral.

Or even quicker: left foot on brake, rev to 200rpm less than stall point, then launch.... smile

Neutral with handbrake on. Don't blind other drivers with your brake lights, especially at night.

What is it? I'm considering an auto barge as I do a lot of stop/start city driving as well as a few longer runs so auto would be easier

A6 Avant 2.7 TDI. I luvs it.

So the consensus is neutral/handbrake.

The 'handbrake' is one of those electromechanical switch jobbies so you can leave it in 'Drive' and just put your foot on the gas for a quick off; the 'handbrake' releases automatically.

Constantly shifting in and out of neutral/park and drive leads to increased wear on the clutch pack. Leave it in drive when at lights or even in slow moving traffic. Use the handbrake at lights if you don't trust your foot to keep the brake pedal depressed. If you are going to be stopped for a few minutes, you would have the car switched off anyway.

Of course if it is a new car with a warranty and you will be getting rid within a couple years, fiddle with the shifter to your heart's desire. smile

Slightly off topic, but do people really find brake lights blinding?. How do you manage on sunny days?.

Yes, that's the way it works. The whole point of an auto is it's built to be left in Drive. Also, if you have a high torque engine it can be difficult to hold the car reliably on the "parking brake".

Leave it in gear and handbrake, seeing as the handbrake works and that is what it is there for. And the bit about not having handbrakes on when stopped at junctions.

Always select neutral and apply the handbrake when stationary for more than a few seconds, leaving it in gear uses considerably more fuel and heats up the transmission fluid.

As the name suggests, park is to be used when the car is parked up.

Driven autos for years and I must admit to simply leaving my foot on the brake and the car in D. Lazy maybe, but that's what I do.....

If it's your first auto, you can look forward to using your left foot on the brake accidentally and performing an unwanted emergency stop

Just to add: most automatic transmissions (these days) have an electric disengagement when the foot-brake has been applied for more than 10 seconds.

Me too, never selected neutral under normal traffic conditions, always thought that's why you have an auto box - to leave it in D.

As I understand it leaving an auto in D when stationary, with foot brake or handbrake applied, has absolutely no detrimental effect on the gearbox whatsoever. Nothing wears out or heats up and any increase fuel use can be measures in gnats cock hairs.

I've been wrong before though.

If you leave an automatic car in drive and don't apply the brake, most will roll up to 10 or 15mph on a level road without the the accelerater being depressed.

You are using the aquivalent fuel to driving at this speed without going anywhere when in drive with the brakes on.

The energy that is being wasted by the torque converter slipping in this situation, causes the trans fluid to be heated and can cause overheating of the fluid during city/town driving in warm weather.

OK, that's fair enough in lengthy static traffic, but surely it's barely anything in stop/start?

Quick Google around and I can't see anyone recommending putting an auto into neutral - someone in one forum noted their manual for their car recommended this when towing, but otherwise it's leave in D

IAM says:
"At traffic lights.
Leave in D. If red, stop and apply hand brake."
