This reminds me of a thought I had about driver-less trucks. The truck drivers who get laid off will be re-employed as security guards to protect the automated trucks from getting robbed.
Only if that’s cheaper than security guards. “Just” hiring security guards may be more cost-effective than “just” making trucks more robbery-resistant.
If a truck has a lifetime of 20 years, that's 20 years' worth of paying a security guard for it.
You really think it could take 20 years' worth of human effort in labor and materials to make a truck more secure? The price of the truck itself in the first place doesn't even come close to that.
