Dozens gathered outside a west Houston Tesla dealership Sunday afternoon to protest and display their anger with Elon Musk, his car company and his recent political involvement with President Donald Trump.

Joan Pence, whose work with the activist group Western Wayne Indivisible has helped grow the West Bloomfield protests, said she has a few basic rules for the protests she has been involved in at the store: Stay on the sidewalk, keep moving and don’t block the driveway.
