I think your people need to have a conversation with Stephen King's
people. A new book "The Mowing" - about a psychotic ride-on
powered by a blackguard Vanguard ...
it all started when a mild-mannered owner puts an Ikea high-back
executive office chair on 'the mower'. The mower then seeks out revenge ...
on the owner ... and subsequent owners ...

Imagine the shrieks (shower scene, Psycho) as the camera pans (close-up)
a very sharp bar blade, as red transmission fluids slowly drips from above...
The camera pans back to reveal red splatter on the white garage wall ...
I choose to stop now.
