I think there are "industrial design" rights, but not sure whether they apply to car designs. There would be an obvious problem of "how similar is too similar"

I think there are "industrial design" rights, but not sure whether they apply to car designs. There would be an obvious problem of "how similar is too similar" given that car types (sedan, wagon, coupe etc.) are broadly similar across brands. In this case the action was based on badges (a trademark violation)
