Talk:Left-foot braking

message: I was under the impression that ALL rallye drivers used left foot braking before the advent of misfiring systems to spool up the turbo mid-turn.  I suppose you're supposed to be able to balance out the acceleration and braking while increasing your revs at the same time, just as if you were accelerating, thus, spooling the turbo.
And, of course, it works with large turbos on street and/or racing to break the boost threshold faster.  Automatic cars, in particular, utilise this technique, especially with a large turbo while drag racing.  I think that LFB in regards to turbo spool should be included in this article.
: It's somewhat moot in rallying, as nearly all WRC-level cars use an anti-lag system. Counterfit 08:45, 10 May 2007 (UTC)

message: Living in a very hilly city I was taught to use left-foot braking in an automatic when preparing to set off uphill from a junction to prevent the car rolling backwards in the interval between letting go of the brake and pressing the accelerator. The automatic equivalent of holding the car on the clutch to set off smoothly. I have been in situations where if I hadn't done this it would have resulted in rolling back into the car behind me.

message: "Also, when the left foot is often used for depressing the clutch pedal this generally requires more force than operating the brake." I suppose if you drive a Corvette, this is true, but I have to wonder how many cars have that heavy of a clutch pedal. Counterfit 08:49, 10 May 2007 (UTC)
replies: text: It's not how much force is required, but how much force drivers are used to. I think what it should say is that drivers are habituated to quickly pressing the clutch all the way down, and that this instinct could cause them to brake much more violently than intended if/when they try to lfb without thinking about it.

thread_title:  The Clutch is normal? 

message: What seems "normal" in one place (for example, USA) can seem as something of an oddity for the rest of the world (notwithstanding Hollywood making New York / Los Angeles the Center of the World). Manual transmissions, even in the 21st century, are still considered the "normal" (non-optional) type of transmission for a passenger vehicle. The exception being, of course, the United States of America (only since the 1950s) and select few other countries worldwide.
For example, in Europe, cars with manual transmissions account for over 75% of new (as of 2008) models, as opposed as only 12% for auto trannies.

thread_title: Sure it's "normal"

message: It seems that there is some agreement that Rauno Aaltonen has been involved in wider application of left foot braking. However, as left foot braking is still fairly obvious thing to do in many situations that existed already well before Mr. Aaltonen's racing career (for example automatic transmission or driving a formula/kart), some additional references would be valuable to confirm if Mr. Aaltonen actually invented the method, applied it to new type of situations/vehicles (rallying and/or fwd vehicles) or just succesfully and extensively used it.  —Preceding unsigned comment added by 193.66.174.253 (talk) 14:30, 12 January 2010 (UTC)

	Left Foot Braking For Automatic Transmission Automobiles	Nov 2013
Left foot braking is a braking technique used by some drivers to prevent parking lot crashes, shorten panic stop braking distances and improve automobile braking in general.
1.	Parking lot crashes:  A recent study by the National Highway Traffic Safety Administration of 2400 gas pedal accidents in North Carolina (driver attempts to move the right foot from the gas pedal position over to the left foot area where the brake pedal is located but hits the gas pedal instead), tend to occur more frequently but not exclusively among drivers over the age of 76 and under the age of 20.
2.	Highway panic stops and automobile braking in general: Lack of concentration by most drivers is the main cause of rear end collisions and pedestrian accidents. Milliseconds count in this situations and undocumented reports indicate that a car braking via the left foot braking method will stop in 30 feet (9 meters) shorter distance when braking from a speed of 37 mph (60 kph), than a car where braking is attempted with the right foot.
What constitutes left foot braking?
Left foot braking must first of all deal with the anthropometrics of seating. Simply put the driver must be able to comfortably sit for long periods of time and at a moment’s notice be able to stop the vehicle in a safe distance.
1.	The driver’s seat is adjusted so that the heel of the right foot, which is  
responsible for the GO mode, rests comfortably on the floor of the car, sharing a portion of the weight of the right leg. The balance of the weight of the right leg is supported by the driver’s seat. The right foot is then in a neutral position neither causing the vehicle to accelerate or decelerate until activated.
2.	The heel of the left foot which is responsible for the STOP mode should also be resting comfortably on the floor supported in the same fashion as the right leg. Again the paramount consideration is that the left foot is in a neutral position, not touching the brake pedal.
3.	It may not always be possible to exactly achieve the objectives of point 1 and 2. Some vehicles do not have adjustable brake pedals so a compromise between the left leg and the right leg positions may be required. The priority must be given to the left leg which must always be in a comfortable position over many hours but always at the ready for a slow down or stop action. The position of the right leg may be compromised from a response and comfort point of view as GO is a lower priority than STOP. Discomfort with the right leg (e.g. toe vs. full foot monitoring or accelerating) can be eliminated by (weather permitting) cruise control. Cruise control also reduces the amount of instrument panel monitoring required and eliminates speeding tickets.
Myths or criticisms of left foot braking:
1.	There are drivers who claim they have witnessed old slow drivers with their brake lights on and therefore they must be drivers using the left foot braking method, prematurely wearing out their brakes. No scientific records exist to back up this assertion and it is more likely that a lazy right foot was the culprit.  It should also be pointed out that a properly trained driver would be following the requirements of left foot driving and therefore the cruise control would cancel the GO mode, thereby alerting the driver.
2.	It has been said that the relationship between the brain and the left leg is not as good as with the right leg. Therefore the left leg does not have the sensitivity required for smooth braking. It is of interest to note that the manoeuver that in the past required the most sensitivity was the engagement of the clutch, which was done with the left foot.
3.	It has also been said that with the left foot braking method, the left foot is only used 35% of the time vs. 85% of the time for the right foot and therefore the left foot does not have the sensitivity for smooth breaking. Unfortunately in most cities with horrendous stop and go traffic this probably is not a legitimate criticism or myth.
4.	Not being able to use the driver’s left foot to stabilize one’s body in a panic braking situation has been also stated as a disadvantage of left foot braking. No records exist of any tests proving this criticism but most car seat belts are comparable to aircraft pilot seat belts and aircraft manoeuvers are certainly more violent.
5.	At the time of the unintended acceleration situation it was suspected that some drivers had depressed the gas pedal and the brake pedal at the same time. If this action was the cause of the unintended acceleration then left foot braking would be at a distinct advantage. However the United States Department of Transportation, National Highway Traffic Administration has mandated that all passenger vehicles have controls that mandate the input to the brake pedal must override the input to the gas pedal so this is no longer an issue.
6.	Drivers that utilize left foot braking may be more susceptible to rear end collisions. Because of the shorter panic stopping distances this may be true, however the same may be said for cars with automatic breaking systems and future cars of the Google design.
