It has ever been that way... when I was a little younger, it always seemed to be Volvos... whenever you heard about a mate being in an accident, it was never a surprise to hear the other vehicle involved was a Volvo... If I have a rummage around, I'm pretty sure I'll turn up my "Bike" magazine sticker "Volvo-aware Rider"
Statistically, they weren't involved in a hugely larger number of bike-related accidents - but it sure seemed that way at the time!
A little later, it was the BMW's turn... they've never been known as Beemers to me - always BM-Trouble-Yous.
We all know that the make/model of a car makes diddlysquat difference, but as you've pointed out, bike riders/pillions are very vulnerable on the road... It's merely a little "battlefield bravado"... You have to ride defensively, assuming that every other road user is literally out to kill you, then you laugh and poke fun at the "tin canners" or be a "Volvo-aware rider" in order to keep your sanity and to carry on being, frankly, brave enough to be a 2-wheeled road user.
Personally, I think you've probably been lucky in your 5k of riding over the past 3 months. My Dad quit riding after doing the daily commute for 15 years or so (as well as pleasure-riding) after he was riding down a street in broad daylight, with no other traffic or parked cars, having made eye contact with a lady stopped at a junction on a side road and watched her sitting there stationary for a couple of hundred yards as he rode down the street, who then pulled out straight into him as he went past the side turning. SMIDSY.
He felt he was extremely lucky to get away with a broken wrist. My Mother was 8 months pregnant with my sister at the time and he never climbed aboard a bike again, feeling that he'd had a wake up call and that he might not be around to support his wife and 2 children if he continued riding.
I'm not a rider myself, but I've seen enough car drivers suddenly become impatient and swing a U-turn out of a line of traffic, without so much as a glance in their mirrors, never mind a bloody indicator. If you happen to be filtering past one of those numpties, completely legally and at a reasonable speed, you've got no chance!
It's just the way it is. You're never simply a woman driver, always a bloody woman driver... You never simply drive a white van, always white van man... You don't ride a scooter, you've got a hairdryer... You're not a sports bike rider, you're an eejit in a babygro... In a Utopian society, we'd all be road users and whatever we rode/drove wouldn't make any difference, but this is real life and perfectly natural
