It's still relatively safe, at least in terms of passive safety (it has a well engineered crash structure, curtain side impact airbags, etc).
It drinks fuel like a drunk uncle drinks wine at a wedding, burns and leaks a little oil, etc. Fuel is very expensive where I live (currently around $8,3 to the gallon), so that's a thing.
But mostly, modern cars are extremely expensive and just not appealing to me as a driver or as an owner. I'd have to go through a ton of repairs and fuel before I'd break even on a new car, I can probably drive my car for more than a decade still before it gets to that point.
Pair that with Mozilla's Privacy Not Included report[0], pervasive tracking in modern cars and bullshit practices like "heated seats as a subscription", and I'm out.
I'm considering just buying a good shell of a car and have it converted to EV when the time comes to replace the Volvo. An EV conversion is about $30-35k for a professional to plan, build, execute and certify. If I want to buy a car that matches or exceeds the comfort, practicality and joy of my Volvo, I'm looking at $60k+ on the new market, at least.
