I think as a passenger as well I'd be more inclined *not* to sit in the front of an eight-seater, or whatever, especially if I was on my own, and if there was a partition of some kind. Kind of think a bigger vehicle gives the impression that the front row is the driver's exclusive space, especially with a partition or similar.
But of course every passenger and every driver perceives these things differently.
It's a few years since I've really thought about these things, but *solo* females are more inclined to go in the back than *solo* males, which is hardly a surprise, obviously. Solo student males are more likely to go in the back than solo male non-students.
So solo students more likely to go in the back than ordinary punters, and solo females more likely to go in the back than males.
If there's two passengers, I never really notice when two go in the back, but I generally notice if three squeeze in the back and leave the front empty.
As I said, it's just about the norm with a group of three female students. On the other hand, I couldn't really imagine three 50-year-old men squeezing into the back and leaving the front seat free. Three older women? Probably more likely to use the front seat, but on rare occasions they might all squeeze into the back.
So only a minority of groups of three will leave the front seat vacant, which is possibly why I tend to notice when it happens.
I sometimes actually ask them if there's someone else to come. A few times three have gotten in the back, stated where they're going, you start moving and they tell you to stop because there's someone else to come
And it's a wee bit like that thing where two or three people get in the back, but they all get in the same door and clamber over, kicking the centre console etc. Which I don't really notice at our night rank in town, because it's a narrow street, and can be quite busy, so makes sense for all to get in at the pavement side.
But there's acres of space at our station rank, and it's like a morgue at times, but you still get three getting in the one side - again, that tends to be a studenty trait - three American tourists or older people generally getting in the back will be more likely to use both doors, even at our more congested town ranks.
Again, that depends on traffic etc. Our South Street rank in town has a bit more space than our Bell Street rank, so at the latter people more inclined not to use the driver's side rear door.
(Another oddity I've just remembered is that years ago cabs at our South Street rank queued against the traffic, so obviously punters more inclined to enter the back at the driver's side next to the pavement. That rank wasn't used much back then, but as it got more congested over the years I think someone somewhere concluded that it might be a good idea for the taxis to queue in the conventional direction, with the traffic

)
But even at our more congested Bell Street rank you get the odd solo getting in the driver's side back door, most obviously if they're crossing the road to get into the cab. They may then sit behind the driver, or shuffle across to the other side - obviously most solos in the back will sit on the passenger side, and of course they tend to get in that side anyway.
But a real rarity is a solo getting in the rear pavement-side door, then shuffling across the seat to sit behind the driver. Work that one out. But that's another scenario that makes me feel a bit suspicious
Anyway, another occassional thing that's happened over the years is solos who get into the front, and spend the whole trip coughing and spluttering
I recall one regular doing that once, and she proudly told me that she'd been told not to come into work in case she infected others with her cold
Of course, that was back then, and that kind of thing has taken on a whole new signficance and meaning with Covid.
And, as per my original point, Covid has also changed the whole front/rear dynamic as well, as illustrated by the original article.
Anway, if I won the Euromillions I'd write a book about stuff like this and, even though no one would publish it and few people would read it, I'd use my own money to publish it
Vanity publishing, I think it's called
(I've used 'driver's side' and 'passenger side' above rather than the more technical 'nearside' and 'offside'. So when I say someone's sat on the rear seat passenger side, I obviously mean the nearside rear seat
