actually if you notice you can see that there is a partition and there is a half circular hole in between the seat of the driver and... the seat next to the driver idk lol, indicating that he can't really see but can probably hear what's happening, so I was half right ohoho
I think that's also why we see "shadows" of what they were doing, because we can't actually see from his seat. I mean if we could then they would have been visible in the background when he was driving right? But instead we get a blank surface with the half circular hole, and we only see them shadows heh
If he's lucky it's one of those that have a speaker and a mic you need to press to talk but maybe it's not the case, seems a bit stupid to have a partition tho if the driver can still hear what you're saying tho... If it wasn't for that half circular thing I'd say maybe the mangaka didn't wanna bother drawing them in the background lol. Also if you are a rich ass bitch that high up in the power ladder then i'd say it's pretty weird not to have a partition, since they are there for privacy and that includes being able to hear what someone is saying ╮( ̄▽ ̄)╭
Little known fact cars like these have a partition so the driver can't really see and can mostly not hear what's happening so it's probably not as traumatic for the poor chap as we think lol, the hormones tho will probably go through....
