I hate subscription services. And I hate money-grubbing corps. Especially when they try to profit off of your own data.
That said, this is not that as infeasible as it sounds. The dev for Tessie reportedly has 400k users. That’s roughly $12.50/month per user. Modestly speaking, if the dev charged their users $13/mo, he’d profit $2.4 million per year. For $15/mo, he would profit $12 million per year.
That’s probably what Tesla is hoping their devs would do. And I’m sure a lot of Tesla owners could afford the fee.
