Is it ok? Yes it is! This topic is getting beat like a dead horse.
I operate manual trans vehicles, and for you nit-pickers I use the left foot for the brake and clutch and the right foot for the accelerator. Sometimes I even left foot brake with a manual but before anyone vapor locks and exclaims I am dangerous you do not know me, my abilities the conditions or the surroundings of the given situation.
I operate an automatic with either right or left foot braking. Before anyone vapor locks and exclaims I am dangerous you do not know me, my abilities the conditions or the surroundings of the given situation. I do not ride the brakes nor do I ride the accelerator.
I operate motorcycles with both hands and both feet ( I am such a rebel).
I operate heavy and small machines in manners that cause the said machine to do various tasks with both hands and both feet.
Have those that are opposed to left foot braking ever tried it? I am sure most have not therefore how can they condemn it? If they have tried it but don’t like it does that mean it is wrong? It may be for them but not for everybody. Some of us who drive use vehicles more than a means of transport to work or the grocery store. Some of us (myself included) try to get really connected with the vehicle when driving or in other words use the vehicle as an extension of themselves and can operate a vehicle in manners that others cannot.
If you do not like left foot braking then don’t do it but do not condemn a practice you simply do not care for. That is like saying manual trans cars are wrong because you prefer an auto.
