Leopard are elusive. I had the fortune to see a mother and cub last year in Namibia. We were touring Etosha and came around a bend of the road; I was sitting in the front passenger seat and had my camera in hand. The sequence below was ~3 seconds.

I saw four of the big five that day in less than 10 hours (no Cape Buffalo in the park). Daylight hunting without dogs is possible but not likely; VW vans don't have enough acceleration (and it's less sporting too).
