BRACE FOR IMPACT
Oh, and if you have a hacksaw, a wrench and a welder somewhere stashed away, you can just remove an intact seat and move it over to where the controls are, or remove the controls and move them to an intact seat, at which point it should be drivable.
I don’t think repairing a seat needs any more than 1 mechanical skill, maybe none, and I know for removing you need none.
For tools, you can often find them in garages, or better yet, in a public works.
