You say that you are "reasonably certain" that "they don't normally" draw their guns in those situations. Then you used the stat about officers actually firing their weapons as the fact to back it up. Am I reading this wrong?
I've gone searching many times for videos and articles on weapons being drawn on black people during standard traffic stops. There are plenty. Those are just the ones that are reported or recorded. There is so little data on "how my experience went with the police". People almost need to be able to leave a review. I can tell you that I am going to listen to the enormous group of black people telling me that there is an injustice against them over the smaller group of police with all the power.
We really do need a community driven first response force that can take care of most of the things you mention. They need people skills for all that, not military training. Soliders and SWAT (relatively speaking) have no business pulling people over for out taillights.
