Not sure, but I have a hunch that it boils down to the fact this was a loaner vehicle driven aggressively by someone unfamiliar with it.
I’ve learned the hard way with rental cars: you can’t drive ‘em like you drive your own car(s). You have to be careful because the dimensions and handling are likely different from what you’re used to.
Pre-COVID I travelled a lot for work and so I drove lots of rental cars. Nothing fancy, generic Avis or Hertz sedans. But it always cracked me up how I'd get in the car, pull out and step on the brake the first time and come to a screeching halt because they are way more sensitive than the ones on my car and I pushed the pedal too hard for that car. You're dead on, blind spots are different, handling is different, sometimes it doesn't matter much but sometimes it's a big difference and it really does.
That’s how I feel right now. I drove my old truck for 21 years and just bought a 2019 model SUV. Day and night.
