The video doesn't play for me, but I saw it on the news. The SUV driver didn't look for plane traffic or stop at the STOP sign painted on the road. I can understand how the driver didn't see the Cessna, but the pilot should have been able to see the SUV and gone around. The runway threshold doesn't show, but it looks like he was low on his approach and would have touched down well before the numbers.
Our local airport has a gravel road that crosses behind a runway and there is a STOP sign on a vertical post along with a sign warning drivers to look out for planes. I worry about boats where I land, not cars.
Edit: The video that was above disappeared, but it must have been the one about a Cessna 172 about to flare for touchdown hitting a SUV that drove across the end of the runway.
