Not in a lot of states, TX included. If it doesn't rise to the level of reckless driving (class B misdemeanor, and requires driving with "wilful or wanton disregard" for safety - I'll dig up the case law that sets a requirement for malice to meet the "wilful or wanton" standard later) then it's not an offense.
From Branch's Annotated Penal Code: "The term wilfully should be defined in the charge of the court. The term wilfully means with evil intent, or with legal malice, or without reasonable grounds for believing the act to be lawful. Lane v State, 16 Texas Crim App 172. Farmer v State, 21 Texas Crim App 423: 2 SW 767 "
Good luck trying to prove that someone was texting or putting on makeup with evil intent.
