It's common but rarely necessary for people to get the largest circuit they can imagine rather than evaluate cost / benefit clearly.

I have a 240v / 20a plug next to my drive way. It cost $300 for the electrician work and $150 for the EVSE. It uses inexpensive romex, didn't require me to beef up my house's 100a service, and 95% of the time recharges the car overnight. On the rare situations where I get home from a long drive late in the evening, with the car under 10%, and drive it the very next morning, the car will have not gotten back to the "normal" charge level, but it's still perfectly usable for 99% of driving requirements... And if I'm in a rare situation where I need to charge it more than I'd get from an overnight drive I can L3 charge it.

Sure, if you're putting 200 miles a day on the car consistently, or if you've got several EVs, or if you've got a huge price difference in your "time of use" power metering contract, having a big pipe between the car and the grid is helpful.

But just as often, spending more than $500 for an EVSE hookup is just not going to be a good way to spend money. Do it if it makes you feel more comfortable, but it's rarely necessary.
