Two main breakers

Why would we have two circuit breakers in the main panel on the outer wall of our town house( built around 1972), one 100 amps and the second for 60 amps? I have been thinking to wire a 6 AWG wire and install 50 amps breaker for Tesla charging into the main panel outside, but discovered two breakers 100 amps and 60 amps. This question may have nothing to do with my intention to install an additional breaker, I just thought, everything that is going into my (town)house should be protected by one 100 amps breaker. What is the the second, 60 amps mysterious one would be for?

60A is most likely HVAC system.

Turn it off and see what doesn't work.

It's a townhouse. If there are two meters too it could be the 60 amp breaker's load has a different rate structure for something like electric heat. Is there a detached garage?

Tesla?

If you have a Tesla why are you even doing this yourself? Call a pro.
