Is accelerating hard in an electric (or any, for that matter) vehicle any more wasteful than accelerating slowly?

My flimsy grasp of physics suggests that it shouldn't be. The energy required to accelerate the mass of the car to 30mph is the same regardless of how long it takes; it's just that the use of energy is spread out over different time scales.

Assuming that the motor is as efficient at converting electrical energy into kinetic energy in the drivetrain at all power outputs, are there any other factors that mean it's more energy-efficient to accelerate slowly? For instance is wind resistance a factor?

Clearly one doesn't want to accelerate to a greater speed than is required, and one wants to decelerate as slowly as possible in order to engage regenerative braking, and in the hope that obstructions have cleared by the time you get there.

I guess my question comes down to: can I make driving more fun by always flooring it off the line?
