Some random notes:
anyone who orders a cheese sandwich and then asks for ketchup deserves to be chased by a vengeful semitruck
wow cars in the 70s just totally sucked. Going 65 in one of those is a terrifying experience worthy of cinema.
Some great moments that presage what Spielberg would become and very inventive with the many ways a semi could terrorize a lone driver. There’s also a lot of repetition though, narrative fat that the director would learn to trim from his all-time masterpiece JAWS.
