In a way it is. Consider precision manoeuvring at low speed. On a manual you use the clutch to inch as the accelerator hasn't got te control. On an auto if you try that you do what my mate did. Revved up to back up a slope, and smashed into the closed garage doors. The brake on an auto functions like a clutch on a manual. Controls the power fed to the wheels.
In a similar vein use of the brake and accelerator together will force a kickdown and makes for smoother and faster driving - mid corner leave the brake on and feed power in, the kickdown happens then release the brake to accelerate away...
It takes me less than 5 minutes to get used to a manual again. You don't dump the first 39 years of your motoring existence that easily.
In similar vein I prefer to drive a RHD car 'on the continent' because I don't have to learn a new car AND remember the 'new' rules: I spent a lot of time over there years ago and it all just 'clicks into place' as soon as I get off the ferry...
Total tosh. See above. It is a vital safety feature to left foot brake. Ther is no otherrway to control the power when takjiong off 'on the torque convertor'.
On my XF its not something you can use for a hill start. Its driven on and off by an electric motor. You HAVE to hold the car on the foot brake and feed in power on the other foot. Unless you want the ugly experience of revving up with the handbrake on, and then, on releasing it, having a completely uncontrolled take off.
