Operating or being a passenger in or on a water/land vehicle at such a velocity or in such a precarious way that the result in losing control of the vehicle and/or simply crashing would result in an inevitable fatality, which would lead to you meeting Jesus himself, hence the term.

For example: Going over 85/90mph on the highway would most likely be considered going Mach Jesus due to the fact that a sudden stop at that speed would kill the passengers of the vehicle. Doing dangerous stunts at high speeds and/or going more than double in a residential, although probably not fatal for the passengers, could be considered Mach Jesus.

Going so fast in a speed boat that colliding with another would not only destroy the boat but more than likely kill the passengers.
“Ahhhhh! Carl! The fuck are you doing?”
“I’m going Mach Jesus!”
“You just went Mach shit yourself.”
