Why would they put the two pedals side by side?
Three reasons come quickly to mind.
!. In a panic situation you can't push both pedals at once if you have to release one to apply the other.
2. You can't rest you left foot (ride) on the brake pedal.
3. When you have three pedals, when you stop, you have to push the clutch and the brake at the same time.
I'll admit I learned to drive a long time ago, but I was taught that number 2 above is a bad thing for a number of reasons.
After 58 years of driving, and a million accident free miles in a semi, I can't recall one time that I had th "think" about releasing the
fuel so that I could apply the brake.
I'm probably showing my age, but I forget that there are probably a lot of people out there who have never driven a straight transmission.
Do they now teach that you should use your left foot on the brake?
I don't think that I could force myself to do that. Besides, how would you operate the dimmer switch, if your left foot was on the brake??????
