^^ I already did this type of tests and I can confirm you that a nicer car, will get you more clearance than a normal car. Especially when they see you in the rear mirror coming faster. Something like, " ohh this guy drives a Ferrari , I do not know who he is but I do not want to deal with him, so I move to the right." or " ohhh, this guy drives a Ferrari, a faster car then me, I move".
"ohhh. this guy drives a Toyota, fuc@ him, I'm as fast as him, he can take me on the right if he wants".
" ohhh. this guy drives a Toyota, fuc@ this moron! "
As well at night in a nice car in general is better, because LED or adaptive bi-xenon headlights help a lot. They see you coming from further, and if they can move to the right, most of the time they will.
And all left lane campers, 98%, they see you as you mentioned in the mirror. Then, there is the blind ones.
