It does happen, but it's weight transfer reducing the natural
downforce (i.e. gravity) , so I guess it can't be strictly "off the
line" since you must be moving when it happens.

Hmmm. You must be accelerating when weight transfer takes place but that
doesn't mean you must also be moving. To actually start from rest you must
accelerate but clearly when you are at rest you are both stationary and
accelerating at the same time. If you couldn't accelerate until after
you'd
started moving you'd be caught in something of a tricky paradox. Doomed to
spend your life frozen in time waiting for a minor deity to come along and
make a small but important change in the laws of physics for you. Of
course
minor deities are all over the place so maybe it wouldn't be a long wait.

Weight transfer isn't instantaneous of course. It's limited to the speed
of
light like most things but that's generally fast enough for mundane things
like cars.

I don't think I said or implied that you couldn't accelerate until
after you started moving. Hope not, anyway!

I think the wheels start turning before you get massive weight
transfer, though, so you'd be off the line even if by a microscopic
distance.

Why am I supporting your point here?

Because the laws of physics are generally persuasive? Weight transfer is an
event in response to a force being created. A force doesn't necessitate
motion. It only creates acceleration. You may be confusing the change in
pitch of the vehicle with the weight transfer but these are entirely
separate things. The weight transfer takes place far faster than the change
in attitude. Primarily because it doesn't involve the actual movement of
something physical like the front and rear of the car.
