Correct translation of 人が運転しなくても走る


From [an article about self-driving
cars:](http://www3.nhk.or.jp/news/easy/k10011283441000/k10011283441000.html)

> 日本のトヨタ自動車は、人が運転しなくても走る自動運転の車を紹介しています。

I'm unsure on the translation of part of the above sentence. Does this mean
that:

  1. Even people who don't drive can travel in these self-driving cars
  2. The car can travel without anybody driving it

2 was my initial thought reading this, but it seems an odd thing to state. It
wouldn't be self-driving if someone was driving it. But 1 also seems odd to
me, since this doesn't seem like something that could possibly be legal.

Which is the correct translation?




The literal translation is 2. The relative clause 人が運転しなくても走る just explains
the meaning of the phrase 自動運転の車 itself. In other words, this relative clause
does not refer to a subcategory of 自動運転車. 自動運転車 has been a well-known concept,
but somehow the author thought it needed clarification.

> トヨタ自動車は、人が運転しなくても走る自動運転の車を紹介しています。  
>  Toyota is introducing an autonomous car, (which is) a car that runs even if
> a person does not drive it.
