More acceleration is always beneficial in cases where you have to perform a safety maneuver or evade something.
Imagine, you are going in the leftmost lane, there is a car a bit too close to you behind (but still fine), in front of you there are no cars, but you aren’t speeding up because speed limits (and you just want to go at a comfortable pace). Someone in the lane to the right isn’t paying attention and trying to merge right into you, you honk, but it will be too late to react for the offending driver. Your only escape here in a slow acceleration car is to break and cause the car behind you to rear-end you, causing a collision and tons of potential injuries. In a car with fast acceleration, you can quickly speed up and that car will (recklessly) merge, all while avoiding an accident.
And that’s not even talking about stuff like avoiding something on the road or stuff falling out of a truck bed in front of you or just absolutely any kind of an avoidance safety maneuver.
