I don't know about yours, but my bike has led me to the ground more times than I'd like - face first in some cases. I have the chipped/broken teeth to prove it. Nothing is foolproof, and everything has inherent risk. It's all relative to crawling, but nothing is risk-free.

The events of Wall-E happened over generations. If your associates have forgotten how to walk already then they never knew how to begin with and were just faking it until something came along to save them. So at least now with a wheelchair as a crutch they can actually contribute rather than just pretending to be productive but getting nothing done in reality.

Then build better guardrails. These are the tools of the future. (And I intend both meanings of the word “tools”.) AI is very good at following rules. In their absence, they require someone far more experienced to drive them properly.
