I bet the poor animal was unhappy about all those people blasting through its larder.
Had a not dissimilar incident a few weeks ago in a deep lane in Lancashire - two deer jumped the fence into the road ahead of us. We both locked up and stopped and a car coming the other way stopped. One deer cleared the fence but the second didn't and it tried about six times to jump each fence, bouncing frantically back and forth, hooves scrabbling on the tarmac until it finally made it over. The sheer amount of energy it expended created a huge cloud of dust, plant debris and fur and my buddy and I were spitting out deer hairs for the next half mile.
