Fast acceleration might be legal but it's also aggressive driving in an urban setting, which is antisocial and cunty, even if there's nobody in the line of fire.
What @AlexD says happens about 50% of the time when drivers have been held up by a delivery (we're living opposite a big building site at the moment) and our road has a 20mph limit which is routinely broken but always broken when people accelerate away aggressively because it's not really possible to do that and not go above 20.
Driving like a twat is less important than not endangering other road users, so I’m not really with you there.
On more than one occasion, I’ve witnessed (both as the victim and as a bystander) someone doing the twattish acceleration and nearly causing serious harm because they’ve not noticed a pedestrian, cyclist or another car.
