So the original Model S had an option for two small rear facing jump seats... The Model X has a 5, 6 or 7 seat configuration... The Model Y is announced as having a 7 seat option (although the two rear seats are small..) Now the 2020 Plaid Model S will have 7 seats... The Model 3 will be the only one of the four *without* the option. I would have thought Tesla would be trying to differentiate their options a bit more?
