What's going on here??

A couple discovered a huge python hitching a ride in their car. The slithery squatter sneaked underneath the bonnet of Marlene Swart and Leon Swanepoel’s car while they were on holiday at the Kruger National Park in South Africa. They were on the look-out for lions when the five-meter python shot out of the grass and disappeared under their car. When the snake failed to reappear Marlene and Leon were forced to endure a three-mile journey knowing the python was somewhere inside their vehicle before arriving at the nearest lookout point.
