That looks impressive, but costs a lot of speed. It’s mostly useful for an aircraft carrier to hide behind another ship rather than directly avoiding torpedoes in open water.
As to acceleration they are something like 2.5 HP to the long ton. So picture a 5 HP car on ice.
There are scenarios where simply being able to stop quickly is evasive. If the torpedo has a 50 km range and the submarine captain assumes it takes you a 1 km to stop, the submarine could attack from 51 km away. When your target is slow to decelerate or change course, you have a greater effective range when attacking from from the front.
All forms of acceleration (be it speeding up, slowing down, or turning) will modify the effective range of enemy torpedoes as a function of launch position relative to the ship.
Consider even a ship moving at a constant speed and heading. If you draw a line around the ship to represent the maximum range of a constant speed torpedo aimed at the ship, that line won't be circular. If you abstract away water drag and assume submarines can move as fast as carriers, then the line would be circular. But in reality drag on the torpedo means that sub can't simply match speeds with the carrier and expect the speeds of the torpedo and the sub to add up. The torpedoe's top speed is relative to the stationary water, not to its launching submarine.
