You can't guarantee that any random EVSE you drive up to will only put
out 30A so a 40A cord gives you a little extra margin. HOWEVER, the
important number is what your car will draw. If your car charger can't
draw more than 25A or so, then I agree. A 40A cord is overkill.
Personally I'd be quite happy using a 30A cord.

Cords for 3 years now...
And mine is cheaper, if you want longer cord I can give it to you at a lower
price
and my cord is UL listed, besides who needs a 40A cord when your EVSE only puts
out 30A?
