ATV acceleration is a bit wonky when you just tap forward or reverse it sort of lurches with too much power, really noticeable when you're trying to back into the garage gently.
It can be abused with the right technique for a huge speed boost to save fuel. Personally, I like it :)
That's what I do when I'm driving around. They can keep it just make it on press down instead of when you let off so it's more controllable imo.
