A vehicle is a weapon, as is a gun. Why do you feel the need to distinguish between the two? Criminals will use this against the police when they are emboldened. Which is precisely what happens when you demonize police officers and call for their defunding. Also when you have liberal judges and DA's letting our criminals with little or no cash bail incidents like this rise.
Silentkisser - this is CAUSATION, not correlation.
Cool, cool.
Now show that the vehicular assaults are targeting police, since the definition includes DUI and driving without a license depending on the states.
Sure, it is possible that emboldened criminals have decided to target cops with cars and not guns for... reasons... but that's pretty strange logic.
I don't know if this site describes actual reports of the deaths, in which case we might get some better idea of what's happening.
