In my opinion, I think the whole electronic braking + transmission system is poorly designed and not optimized at all.
Compared to my previous car which had a "mechanical 5AT", I like that my M35i 'disengages' the gear from the engine when sitting at a red light. There are no annoying vibrations transmitted to the cabin.
However, I dislike how there is a noticeable 'thunk' when I release the brake to take off. And, the transmission becomes unpredictable when I'm creeping along in slow traffic. It becomes a jerky start & stop and sometimes the brakes will 'shudder'.
With all this shit going on, it's not too surprising that acceleration can also become unpredictable. For me, these 'NEAR DEATH EXPERIENCES' occur when I release the brake in the left turn lane and slowly creep forward. I can feel my heart explode as I press my right foot deeper and deeper...
