The limits and capacities of these tires are far greater than any stresses 60psi at slow speeds on paved roads puts on them. Our cars are mass produced for all possible extremes of conditions at once. The psi guidelines are a lowest common denominator kinda thing. The consumer information does not try to represent the absolute extreme capacities of the vehicles that the engineering has identified. So don't go near the stated sidewall if you choose, but that's not realistically a thoughtful choice about safety, though you clearly think it is. It's about your preferences, your applications, and the conditions in which you drive your car.
He'll keep an eye on his tires, as should you. Your softer tires face different blowout possibilities than his do at 60psi. He's better off in some conditions at 60psi than you are at 42. Hydroplaning for example.
Gotta go to work. I hope that's clear and useful. Have a good day.

The extra 6 PSI I have in my tires now make my front drive wheels spin with little effort. That didn't happen at 36 PSI. The reason FE is increased with higher PSI is because of the lower rolling resistance associated with a smaller contact patch - and thus less maneuverability and stopping power. If you want to transform your tires into hard plastic discs at 60, 80, or (heck, why stop there) 100 PSI - that's your prerogative.
Are you prepared to accept liability for suggesting that people over-inflate their tires beyond design specs? It's important to let others know who to sue if / when their over-inflated tires are found to be the cause of an accident.
