Unless you are badly injured or a small child, coyotes are not a threat. Credible reports of healthy coyotes willingly attacking healthy adult humans are basically non-existent. There's always something else going on that precipitates the attack.
You are far more likely to be killed by the heat and lack of water in the Mojave than by any animal.
Edit; unless by "coyote" you mean cartel-affiliated human traffickers, in which case, yeah, they definitely are bad news.
