Hypothetically, if one wanted to shift into neutral to coast without revving their engine via engine breaking, such a feat would be impossible with a manual car (or very very risky, as you'd have to shift through anywhere between three and six gears as fast as possible to avoid engine damage by overrevving)

Implemented in V20.0.0.

So, I can do this, but I can't assure it'll work properly all the time due to the fact shifting is coded to either be up or down, and not a specific gear selected. So I can send off 6 downshift packets at once, but if they don't batch together then you'll end up with one perhaps being handled 1 second after the others, so you'll be in 1st gear for a little bit.

If, however, you want to only go to neutral and not auto-shift back into gear from neutral, I could see about coding a specific packet for that. That work?

Sounds good to me, being able to emergency neutral is better than nothing
