日産自動車、「プロパイロット2.0」(インテリジェント高速道路ルート走行)をスカイラインに搭載
Nissan's announcement page says it won't work in tunnels and the driver must take over.
日産「プロパイロット2.0」で“手放し運転”が可能に!果たして安全なのか - 価格.comマガジン
開発者は、「実際の高速道路の走行では、(ずっと走り続けられるといったことはなく)時々ハンズオフ(手放し)がキャンセルされ、操舵をドライバーに戻すことになる」という。
Nissan developer of ProPilot mentioned that if you drive actual highway, you won't be able to let ProPilot drive forever, hands-off driving will be canceled, and the driver will need to operate steering wheel.
So in this article it is quoted as a comment from one of the developers of ProPilot, but it's not a recording so it's difficult to tell the truth. However if L2 worked in tunnels, I would write the press release differently to remove source of confusion, if I were an Nissan employee.
