So you're saying that people get a new Tesla for free, then only pay $100 bucks per month for 'extras'?
Tesla would definitely collapse seeing that they're not getting paid for making that Tesla car in the first case. They'd be broke within a couple of months.
No, Tesla already sold these cars and took people's money. They continue to sell cars the same. This is about charging the existing and new customers $100/mo because it's a number Tesla thought of. It's not for extras it's for all non-legally-required safety functionality- e.g. the tablet screen, a/c, ability to adjust your seat.
