Not quite a car, not quite a motorcycle: a vehicle built for one

But in +100,000km of total riding time I've had very few injuries, just scrapes and bruises because I'm always wearing boots, helmet and gloves as a minimum.

I've high sided on a track twice (too fast into a corner, lost traction, immediately got traction back and flew me several metres in the air). And I've low sided from road debris twice on public roads (once on a round-a-bout at low speed) and private roads (oil slick in a private car park).

I imagine this vehicle for the average person who doesn't ride a lot with the view of safety first would be safer in this than a motorcycle. But I agree with your and the OP's point above yours. An economy budget car would be a safer and equally viable purchase.

Even if people drive their cars safely, the huge difference in performance means they're more likely to get in trouble on a bike.

But I too have ridden heaps of miles in a previous life when I'd habitually tour the US on two wheels, and there can definitely be frustrations and risks with inexperienced passengers.

From having to convince them things like No, your Keds are not satisfactory for us to go riding. Yes, you must wear a helmet and some pants and gloves would be smart. No, you should not lean into the corners, just be a predictable appendage of the bike especially at low speeds. No, you should not put your foot anywhere near the chain/chain guard, regardless of how annoyingly high the rear pegs are on this superbike. Yes, you must hold on to me and not let go and bail in a panic, yes, even if the front end comes off the ground and you're looking at the sky briefly.

This walk down memory lane reminds me of the time I had to give my ex a ride to work when her car wouldn't start. I had an 04 R1 back then and she never rode on the back before because she was terrified of the thing, and I never had taken passengers on it because it was so poorly suited to it, I actually had to put passenger pegs on for that trip. Just breathing on the throttle in first with her on the back would pull the front end off the ground, it was comically bad with the combination of short wheelbase, high CoG of the passenger on that steep tail, and liter bike tq. When she got off at work she was shaking with fear and said she almost fell off the first time the front end came up a bit and that was having significant experience riding on the back of my previous sport-tourer.

On that previous sport-tourer years prior we had an annoying spill where she was leaned over to see around my helmet while we were riding in an unfamiliar part of Chicago when the front end locked up briefly over an oily patch on Ashland braking for a light. Due to her leaning to see around me we were down and tumbling down the road in the blink of an eye, it was rather shocking but things happen quickly when the front end locks up with a passenger leaned over. Fortunately we walked away with just skinned knees, bruised egos, and a ground through stator cover.
