Tesla Semi towing 5th wheel

As an scholar, in the academy there are plenty of SAE level 4, however in controlled environments. In the mass production model, as far the peer review go, only the MercBenz intellidrive and Tesla are the one testing this approach on the real roads. The google one too, but not that far away.

keep a close eye on uber in the next 18 months, you're going to be surprised

although i suppose that's sort of an exception, those will be volvo XC90s given by volvo and integrated closely with uber's self driving systems.
if you're referring to full autonomy as like an option package as a car in a show room, ford and argo AI will probably be doing city specific level 3 by 2021 ish.

is in, within some small collection of cities the car can roam around freely, but cant go outside city limits

> Only in controlled environments, as i said.
