Sally tells Matt "Turn right ahead, but be careful there is a tree down in the road." Moments later Matt turns LEFT and stops at the downed tree.
Sally takes 8 seconds to get from the cliff back to the car. Matt waits until he hears her start the car before he runs back to the car-taking 20 seconds (2.5 x the time it took Sally). He should have at least gotten there in the same amount of time, but even so, if he had arrived in 16 seconds he would have been there before the car sped away. Not plausible.
Right out of the gate, 1:1, host John Newland surely hoped to nail it. When he spread his hands and arms to the sides, motioning to the set the viewers are about to watch, notice his left hand bumped the bar.
