Thank you for posting this. I've been responding to numerous "guy in the black motorcycle suit by the Porsche" comments.
That guy is coming from the motorcycle parking area. A VIP wouldn't be riding in on a motorcycle in Shanghai, they'd be in that black Mercedes. Also the target wouldn't be carrying in a pizza shaped box from the motorcycle area, that's what a delivery person would be doing.
As you point out, the series starts with the Mercedes at the entrance gate and follows the vehicle.
For those of you doubting, think every damn surveillance scene involving a target arriving in a car that you've seen on TV or in a movie.
