At very low speeds (around 1-5 mph, perhaps 1-10), my car is in its creeping range of speed tapping on the brake pedal (going from "power" to "charge") will produce a noticeable jolt. If I'm above the creeping speed, and tap on the accelerator pedal (going from "charge" to "power") will produce a similar jolt. Lowish speeds like 5-15 mph has the same effect but not nearly as severe.
