Even people who drive small cars do so in a way that they believe to be safe. Even people who drove before "modern SUVs" existed did so in a way they believed to be safe. Drivers of SUVs are not the ones risking the lives of others, while the "rest of us" are being safe and responsible.
When car accidents are as common and tragic as they are, the fault isn't with individual drivers. Drivers try to drive safely, and generally do their best under the circumstances. They're just regular people, like all of us. The fault is with the system: road design, vehicle design, incentives (city design, etc), and education.
