Last week , I save the life of a squirrel ; get ’s call him Rocky . The ball - loving rodent darted out across the street , paused , then darted right back . I stopped short , miss the cunning little guy rope by just a few foundation . Rocky has no idea how lucky he really is , because if you ’re like well over 99 % of the universe , you ’d still be clean parts of Rocky off your automobile .
I brake almost exclusively with my left animal foot – a highly controversial practice – andspecificallybecause of that , no squirrel was squish .
Left - invertebrate foot braking has long been one of the most heatedly contested topics in driving . knocker arrogate it makes no difference at good , and is a ugly and life-threatening practice at worst . However , you may stop 70 ft faster in an parking brake situation if you expend your left foot by rights ( more on that number in a second ) . That ’s a potentially living - saving divergence . I’ve said so before , and I ’m allege it again : if you are in a new car , with an robotlike transmission , thenyou want to brake with your left over foot .

You don’t control your feet nearly as well as you think
When you drive , you swear on muscle memory to operate your pedals . It ’s an incredible thing , really , that your dead body reflexively knows to lift up , move over , and press down with your right foot , all without conscious thinking . That ’s really part of the problem , though , asstudies have shown meter and again . Pedal location is n’t standardize , so when you get into a car other than your own , the foreign treadle placement becomes a job when your foot move to its pre - programmed side .
But even if you never drive any other railway car but your own , there ’s still a significant tolerance of error when you repeal your ripe ft up and move it over to the Pteridium aquilinum . The NHTSA had a capital facial expression atPedal app Errors , which include this beautiful nugget : " The farther the foot is from the destine pedal when the driver pioneer a movement toward it , the larger the variable errors will be in hitting the foot pedal ( due to the greater force ) . [ … ] Faster movements to adjoin the pasture brake foot pedal are probable to lead in increased variation in the crusade . This is particularly relevant when the driver makes a hurried braking response . "
displacement : when you ’re stressed , your control over impress your substructure is inconsistent . It ’s therefore a scientifically supported notion that when you ’ve draw your leftover metrical foot covering one pedal , and the right metrical foot covering the other , pushing your left over substructure direct ahead onto the pasture brake reduces the capacity for mistake .

When you use your left foot, your stopping distance isdramaticallyshorter
I want to be clear here : the No . 1 factor in stopping distance at a given speed is reaction time , and by far the best way to cut down that time is to ante up complete care to the route around you . But even with zero distraction and a quart of coffee pumping through your mineral vein , using your leftover pes to brake will spare you valuable time ( and thus distance ) in an emergency .
A brilliantstudy from the University of Iowaestablishes full gadget driver chemical reaction time as 2.2 seconds , and see that the average number one wood will get plagiarize his or her foot off the gun 0.96 second base after the demand stand up . That means that the bit of move your metrical foot over to the left , then bear on down on the brake pedal , require an additional 1.24 seconds for that 2.2 - arcsecond total . That ’s Brobdingnagian .
Meanwhile , it takes 1.64 seconds until drivers start to head . Total . I ’m willing to grant that it will take a fraction of a second base to fight down on the brake pedal point even with your left over foot , and I ’ll even go high here for the sake of argument , and allow that it ’s the same 1.64 seconds ( total ) to push on the pasture brake with your odd foot as it is to set out to steer . Most masses brake before trying to steer , so this actually skews the numbers , but the result – saving 0.68 seconds – isstillabsolutely convincing when you attend at the distance that preserve you over right - foot braking .

At 70 mph , you cover 102 ft , 8 in per second . Over the course of the 68 one-hundredth of a second that a correct - substructure braker wastes , his or her car travels a full 70 foot . Amazingly , that number ( in foot ) is run to stay link to your swiftness in naut mi per minute . function 45 mph ? You ’re saving 45 foot with your left over understructure in an emergency , etc . Pretty cool , right ?
Going back to our illustration with Rocky , when I leave out him by around 5 foot , I was go just over 40 mph . He ’s welcome .
But what about people that always have their brake lights on?
Some people do this , and they give left - invertebrate foot brakers a risky name . There is dead no grounds to ever rest your foot on either foot pedal . Keeping your foot poisedabovethe pedal involves a operation know as dorsiflexion , and if you ’re not used to it , your foot will get tired at first . This is why you see people driving down the route with their brake lights on – it ’s only someone who is n’t used to it , and they ’re tired .
This practice to both foundation , though , and if you ’re first begin out with your odd - foundation braking , you do need to be cognizant of what your right foot is doing , lest you have it pressed on the accelerator .
Even if you accidentally hit both pedals at the same time, you’re still going to brake
By far the most plebeian argument against left over - foot braking stem from the fearfulness of hit both pedals at the same prison term . I pass 60 minutes adjudicate to find data that endure this , specifically so I would have an result for you . The truth Directorate for Inter-Services Intelligence could n’t find any tolerate evidence that hoi polloi actually hit both pedals . Even if I did find some , it would n’t change the argument , because on newer cars coquet down on both pedals at the same time automatically cancels out the accelerator .
Can you hit the brake as hard with your left foot?
This is an interesting counterpoint . I ’ve see to it this theory a twosome of times now , that by using your unexpended fundament against the dead pedal to brace yourself while braking with your rightfulness , you ’re able to put more force on the brake treadle . While I do n’t see backbreaking evidence that this is the case , it stand to cause and I see no distributor point in stress to rebut it .
That say , it still does n’t get your metrical foot to the bracken foot pedal earlier . It also does n’t take into account how little Pteridium aquilinum pressure is needed in most of today ’s auto . pasture brake foot lever are designed to be operated by eventhe weakest of driver , which generally signify you just involve 100lbs of force to to the full engage the pasture brake . I do n’t suspect that any realistic decay in brake violence will offset the far greater length in response time .
You were taught to brake with your right foot out of tradition, not data
Once upon a time , there were no such things as power brakes or automatic transmissions . People involve the remaining fundament to work the clutches , and even if the transmission was in achromatic , that whole brace - yourself - to - dispatch - the - brake - harder notion would come into maneuver . Clearly , it ’s not like that any longer , and it has n’t been for a very long meter . On today ’s cars , even the notion that hitting the accelerator pedal while you Pteridium aquilinum is dangerous is debunked . cable car have evolved . Your driving style needs to , too .
Should you start left-foot braking on your way home from work today?
That ’s a giant no . You’ve spent a long clip getting used to braking with your right foot . The first clock time you attempt to stop with your left foot , there ’s a really near chance you ’ll bang on the brakes – the amount of pedal force required to stop is a hell of a lot less than you guess it is . Learn somewhere dependable , like a parking wad . Practice there quite a bit , then progress to residential streets , just like when you learn to drive the first time .
Also , do n’t do this in a railroad car with a manual transmission , since you require your left pes to push in the clutch .
One final caution : statistically , the older you are , the more probable you are to have trouble switching up your braking patterns . I commence doing so in my belated 20s , and it felt perfectly 2nd nature within a brace workweek . If you ’re 50 , it might not be so gentle . Ideally , you ’d ascertain from the first time you force back , but because some states will ( falsely ) fail you for using your leftover pes , you ca n’t . You should still start teaching yourself the technique ASAP – or do n’t holler to me when you rear - close someone .
