Howard plugged his new film on the show and tried his luck in the show's ongoing "Star in a Reasonably Priced Car" competition, but ended up near the bottom of the standings.
Howard's sluggish time of one minute, 49.9 seconds in the Vauxhall Astra Techline placed him second-to-last, only above Genesis rocker Mike Rutherford.
The director blamed his time having to drive with a left-handed stickshift. He told host Jeremy Clarkson, "First of all, I will say the right-hand drive and the gearshift on the left was a concern to me. It definitely threw me."
He then jokes, "I implore anyone who has any interest in seeing my movie Rush, you know, I didn't drive in the movie! Real drivers drove in the movie."
Clarkson teased the director, "We finally found something you can't do. Good at directing, brilliant in Happy Days, a charming human being... but utterly crap at driving."
