Centaur and a Devil's Ride

[Techcaliber]

Hello!

I'm going to be running DiA and one of my players is going to be playing a centaur. This player likes to push the boundaries of the rules (not in a bad way though), and argues against some things that would be common sense. Here's the question: would you allow a Centaur to ride an unmodified (meaning made for a regular humanoid) Devil's Ride? I don't know if this is going to be a problem, but it's the only one of the Infernal War Machines that it would be a problem with.

Thanks in advance!

For some reason I am trying to imagine a horse riding a ATV or a wheelchair and I think no.
You are going to be at least one half of a horse overflow.

If you want to be nice you could say that they can sit in it if made for a larger demon/devil i guess but they will have disadvantage on checks to use the vehicle.
Or give them a devil ride of their own that is basically hellish training wheels they can put on their hooves.
