Unless you're doing a burnout the whole way of course. It might help a little, but I can't see it being more help than weaving aggressively.
Riding hard is what warms up your tires in the first place (leaning, turning, etc.), so how is that different (except for the speeds involved perhaps) from weaving for a while?
Don't confuse heating up the brakes with heating up the tires
Why can you see hard braking, but cannot see hard acceleration?
it is effectivley the same thing. When you brake, you are creating a resistance on the rubber against the ground on which it is rolling.
(creating heat)Hard braking would do this faster.
So too, is what happens when the tire(rubber) is under hard acceleration.
In either case, you are not really creating friction.
Only because, friction is always present. If there were no friction you would not be able to accelerate(move from a standing position)
and, conversely, you would not be able to stop(if you were moving).
So you are creating heat, when performing one of these two action.
And yes, the heat starts off "localized", at the point of contact. That is most understandable(hard braking or hard acceleration woould not create heat in your left rearview mirror
so the heat starts at the point of contact and then heats the entire tire. you do not nead to make road contact in all parts of the tire to heat it up( if you ride straight for a while, your tires will be sufficiently warmed up).
