A significant statistical difference in reaction times between left and right side hand and feet...
Interesting, left side approximately 10ms slower, but more consistent.A significant statistical difference in reaction times between left and right side hand and feet...
In a specific situation where you have assessed a risk such that you may need to brake rapidly and still need to maintain speed* you believe you can get your right foot from the accelerator to the brake in less than 10ms?
- you have already adjusted your speed downwards, but do not at this time need to come to a stop.

As I may have said once or twice, I brake manuals with my right foot and autos with my left foot. There is no benefit in doing it but I'm not look it for benefit. I'm not looking for advantage. I'm not doing it to be clever. I don't press both pedals at the same time. I don't cover the brake pedal all the time.

Yes but in all other circumstances it's worse. That's why there can't be a consensus. We really don't know which advantages are most beneficial. It becomes even more complicated. if you factor in, we also cannot know if covering the brake with the left foot means that, in the same situation, that driver is travelling faster.

Where you are just driving along with your left foot on the rest or floor then just use your right foot. If on cruise control it makes little difference which you use. In an emergency no reason not to use both, auto brake pedals are really wide. There is the risk of pressing the accelerator at the same time of course, something that happened to me a couple of times early in my driving history in a manual when using just my right foot, never in an automatic though.
I agree that you should learn modulation and control off the road, though new drivers often have no choice when beginning.

You keep saying this, but as usual you have zero evidence. I can tell you from my personal experience that I do not travel faster when covering the brake pedal with my left foot, probably because I am making a conscious decision to do something with the purpose of increasing the safety of myself and others.It's very simple - travelling at the same speed, same driver etc.., you will stop quicker if you can LFB and are covering the brake. There's been no valid argument against this, no data that shows anything other than a 10ms difference between legs, expert drivers confirm the LFB benefits. and people who do it daily also confirm the benefits.

I don't eally disagree. It's just I'm probably not, because I don't find it a very comfortable position to maintain.
Yeah, that will be very dependant upon the car, pedal layout, seat position, even the size of your feet.In my current car, my heel is always on the floor in front of the brake pedal.
It simply rotates to the left to rest on the dead pedal or back up vertically to cover the brake. I'm certainly not driving along with my leg hovering in mid-air as that would be very uncomfortable.

I don't eally disagree. It's just I'm probably not, because I don't find it a very comfortable position to maintain.If someone wishes to do this then that’s absolutely fine but there is obviously no sanity in actually promoting it as sensible practice to the wider public.
If the manual gearbox disappears completely and the world goes 100% two pedal then it would seem logical for the brake pedal to end up being repositioned so that it is purposely designed for the left foot, the the foot rest becoming sprung so that in an emergency it can’t impede panic braking etc.

And some people need data or they can't even wipe their own arse.
You don't seem to understand that unless you can prove something with data then its a theory at best. Some of the reasons/theorys/arguments given on the thread to support lfb a modern auto are laughable at best, some a little more believable but none have been studied and proven by any organisation who can endorse the results of a proper study. I spend my career demonstrating to people in various business that what they think about how their own business works is usually not true, then they use the data to improve their business and make more profit and usually sell the business.
What we have discovered really on this thread is that people who have experience of doing it do it, other people that don't do it, THINK they can do it perfectly under pressure and that its ok to put other people at risk while they learn.

Seeing as the pro rally instructor recommends LFB even on the normal roads, I think I'll follow his advice in preference to yours thanks. Your argument is weak and all over the place, much like your left leg I suspect...
Which 'pro rally instructor' are we talking about? Not the american retard in one of the youtube links in the BMW I hope?Edited by JimSuperSix on Wednesday 9th October 19:54
Plenty of rally drivers don't lfb in rally cars and I bet most would never recommend it in a road car.
