Me too. I actually looked into that a few months ago. In Boston Massachusetts, there is this place: https://www.teslarents.com/
But we were going to San Francisco not Boston, and there was nothing that I could google up. With the exception of Oslo, Norway; I've never seen so many Teslas as I did in the Bay area, but it seemed really hard to rent one for a few days.
Maybe by the next time that I'm there a Tesla 3 will be standard at Hertz, but in 2021 you'll be lucky to get a Nissan. The competence and availability of even that, was low.
