I don't think you're quite getting what really causes these safety issues. Limiting cars' acceleration or speed still leaves 6000lb SUVs with double the momentum of 3000lb sedans. Most car crashes don't involve anyone going 100mph, but heavy SUVs with bad visibility are frequently involved in accidents. Because they're technically "offroad vehicles" (even though most of them never go offroad), SUVs are allowed to ignore many pedestrian crash standards. The NHTSA also crash tests vehicles against other vehicles in the same class, so the true consequences of SUVs don't show up in their tests. There's also the issue of children being run over in driveways and parking lots by SUVs with massive blind spots.
