Med kit is a band-aid kind of item which is a common thing that was simulated from real life, and if you're gonna be referring this to an armor kit usage, it just doesn't make any sense and this whole suggestion also makes no sense from what I've read, it's merely just skill issue type of reasoning and no proper argument set on behalf of this.
I am fine with what's currently on, I can take on the cops tank easily if I drive properly and manage to escape but it also depends on my luck on whether they suck at shooting and driving or not.
