In my country lightning strikes are rare, the equipment on each end of the link costs substantially less than a fiber splicing machine, and we get bonded earth connections as a matter of course.

I agree it's worth keeping an eye on your earthing, of course - if you get a noticeable difference in ground potential and you plan to plug in an EV charger outside in the rain, you might need some extra grounding. Unless your garage, your EV and yourself are all on an insulated concrete slab.
