There's no vehicle between you and the rhino at Ziwa, just a ranger, a rifle nobody expects to use, and a very slow, very deliberate walk across open grassland.

You hear a rhino breathing before you're anywhere near close enough to see it clearly.
Southern white rhinos were locally extinct in Uganda until a reintroduction programme brought them back to Ziwa. Walking up on one, on foot, is still the closest thing I've found to time travel.
