Why must you hold the brake down before starting the engine?

Just curious: why is it required that you hold the brake pedal down before pushing the start engine button if BMW employs the new Start-Off Assistant feature that prevents your car from rolling backwards when starting it on an incline?

It's just a way of telling the car you want to turn the engine on, rather than just the electronics. Plus, you're going to have to press the brake pedal to switch into gear anyways.
That's true.

Wow, I didn't know pushing in the brake was such a difficult task.:jack:
Who said it was difficult? I was only asking why you needed to do it.

While I never saw this in the media and never looked closely at an Audi 5000, I was told by someone who used to work for them that the gas and brake were both narrow vertical pedals while American cars had wide horizontal brake pedals and narrow vertical gas pedals. The similarity of the pedals may have contributed to less attentive driver's making mistakes.
Heh. This reminds me of a time I was driving my dad's Jeep Grand Cherokee and I was backing out of a parking space. I went to hit the brake to then switch it in drive but the brake wouldn't activate so I pushed it harder. :rofl:

Turns out my foot was on the gas and because my dad's jeep has that new 5.7L 330HP HEMI in it I went about 0-30 in reverse in about a second. Haha. Luckily, no one was behind me and I quickly hit the real brake. Heh.
