    Physics says that in a collision, the heavier vehicle will always come out better. Higher mass means more resistance to acceleration, so it will take longer to change speed and impart less force on the occupants. This is one reason why buses sometimes don’t have seatbelts, when the bus collides with much lighter cars it will be largely unaffected.

    If everyone has a heavy vehicle, it’s worse overall because of higher kinetic energy causing more dramatic collisions. And obviously significantly worse for everyone outside a car.

    Hence the arms race.

      Which is offset by the lack of safety regulation, high center of mass, heavier weight to crush the cabin in a rollover, and much higher likelihood of running over your own kids.

      Stop spreading propaganda by cherry picking,

        Citation needed. SUVs tend to be modern which would generally have stricter safety regulations

        high center of mass, heavier weight to crush the cabin in a rollover

        I wouldn’t have though that rollovers are a common cause of deaths or serious injuries in cars. The higher center of gravity is going to be offset by the wider wheel base, so it depends on the car.

        Traction seems like a much bigger problem, although many SUVs solve this with bigger wheels.

        and much higher likelihood of running over your own kids.

        Agree 100%

        Stop spreading propaganda by cherry picking,

        Look, fuck SUVs, obviously. If you aren’t a psychopath you should not feel safe driving those things. My point was specifically about the physics of collisions. What you’re bringing up can’t be answered with physics because it depends on the details of the car, we need real world statistics to continue this conversation.

          “Buy a new big car because it will be later year than a new small car and thus have newer safety features” is an incredibly wild way of drawing the exact opposite conclusion to the one you should have from that data.

          what? that makes no sense. SUVs in the US are generally regulated as light trucks, which have historically had laxer safety requirements for a given model year
