How to use left foot braking on street

This article will show you on apply left foot braking on street.  Left foot braking is not a good driving practice, and in fact it's practice on street is discouraged.  However I find LFB (Left Foot Braking) is useful, especially with automatic car.

Disclaimer: this article deals with uncommon driving practice.  I do not advice you to try and practice this at local street.  However if you decided to practice any LFB, you must adhere to this following term and condition: I can't be held responsible for any loss or damages incurred by applying the tricks.

Background

Left foot braking usually usually used in racing, so racer can corner faster and tighter, resulting faster lap time.  LFB not only used on rally, F1 drivers also uses this technique. 

When practicing I advice drivers to use LFB when his or her car has ABS + EBD, since most people will push the brake too hard with left foot, and ABS + EBD can help control the car.  Moreover I advice only driver of an automatic transmission car practice this.  LFB will produce same effect as heel and toe, at easier application.  That's why professional F1 racers use LFB instead of heel and toe.

PS: ABS + EBD and left foot braking will allow driver to do more extreme and faster manoeuvre. 

Although LFB can be used in racing and will effectively improve the timing, I do not advice to use LFB in street racing!  If you wanted to race, just go to a local race track and race legally!

Left foot braking to control the car in slow speed

LFB is useful especially when moving slowly in a road with uneven heights.  LFB allows the driver to control the car to move slowly and stably.  How to do: press the brake fully with left foot, and then press the throttle slowly with right foot.  Slowly release the brake to bring the car forward, just like what you did with manual car's Clutch.  When you need to slow the car, just press the brake with left foot. 

Moreover LBF can also help you controlling the car on tight parking lots.  This will make your slow speed manoeuvres safer and more precise.  This technique is particularly useful on jumpy car such as Toyota Vios.

Left foot braking to reduce reaction time

It means faster reaction, standing by the left foot on brake pedal means 0.5 seconds faster reaction time.  Use with abs car only.  0.5 seconds at 80 km/h is 10 metre., so it saves your actual braking distance by 10 metre.  Something that could save your live and troubles.  This trick is very useful in street racing :)

Imagine that you are relaxed driving on a highway at 80 km/h (22 metre/seconds).  You are playing safe by tailing at 20 metre away from the car in front of you, quite far, but not quite right.  Therefore you have 0.9 seconds spare between your car in the other car, more than the recommended tailing distance of 2 seconds.  Suddenly the car in front of you make an emergency brake and stopping.

Assuming you are average 30 years old driver, you will require 0.5 seconds to react.  Please don't start quarrelling me that you or Michael Schumacher react faster!  Then you will move your left foot to the brake pedal in another 0.5 seconds.  You will waste 22 metre on the process.  In fact, some people even forgot to move the left foot over the brake pedal, resulting pressing the throttle deeper when in panic, therefore instead of braking the car goes even faster!

Now your distance from the car in front of you is only 28 metre.  An average car with a good brake requires 50 metre to brake from 80 km/h to a complete stop.  If you are driving a super car or sports car, the distance could be less, however if you are driving a family van or SUV, your car needs more distance to come to a complete stop.

Assuming that you drive an average car, and the driver in front of you also droves an average car, as you can see on the illustration if you are lucky, after braking, your car's nose will touch other car's boot.

  • RED bar: the reaction time
  • Orange bar: braking time
  • Yellow bar: your car's stopping distance
  • Blue bar: other car's stopping distance
  • Black car: your car before braking and after braking
  • Red car: the car in front of you before and after braking

On the other hand, this illustration shows that LFB will save you 8 metre spare distance, therefore this could save you from additional problem.

Although I do not advice to tail tightly, LFB will improve your safety when tailing at such unsafe distance.  I don't tail people too tightly, I always kept at least 2 seconds distance when tailing.

Left foot braking to make distance from someone tailing too tightly

LFB can be used to to buy some distance from tailing you too tight.  A gentle touch on brake pedal will lit the brake light on, making someone behind you to brake.  While right foot is pressing the throttle for maintaining same speed, resulting in increased distance.  Therefore you can buy some distance from him using this technique.

Crude but effective. 

However, don't use it too often since people will then know and didn't brake when you really wanted to stop!

LFB for stopping and starting in steep slope

You can also use left foot braking to maintain a car with automatic transmission still in a steep climbing slope.  Sometimes in a steep slope an automatic transmission car tends to move backward even in D or L position (my car uses L, however other car uses 1).

Left foot braking comes to the rescue.  Just hold the brake pedal with your left brake, and push the throttle a little bit with right foot and then slowly release the brake pedal just like what you did with manual car's clutch.

Your car will move slowly and smoothly without all the usual jitter and backward movement. 

Additional note

Average driver's left foot usually pushes the brake pedal with twice power of his or her right foot, therefore you'll need to train in doing LFB slowly but sure.  Otherwise, on a car without ABS and EBD, your car might skids out of control.

Conclusion

I find left foot braking is especially useful for everyday motoring.  As long as you train before doing LFB, you can do it safely and increasing your overall driving safety. 

However, I don't know about you, since other people's conclusions might be different.
