Perhaps install two high capacity circuits, for two EV cars. It is just some wire and circuit breaker costs, up until you install the actual charger(s).

One of the interesting future things about owning an EV is that during electrical mains power outages the plugged in car and wall mounted 'charger' can act as a giant UPS for the house, providing hours of AC runtime. Do any of the Tesla compatible chargers offer that capability? The house wiring would be slightly more complex to handle the house load transfer, so worth planning for if that is of interest to you.

I have a fair sized electrical sub-panel in my garage. I find that having more capacity and more circuit options is a good thing, especially in a garage where the space can be repurposed for many different possible things.
