There needs to be a weak point in the driveline somewhere, preferably somewhere cheap and easily replaced and that's usually a CV joint or a driveshaft, they tend to shear at the end of a spline and hopefully the rubber boot will keep the remains in place until you stop the engine.
As I proved at Cornbury Rally Show (2011)..... albeit after a stupid man made yump
2000cc Lancia Beta shafts
Just make sure you have spare drive shafts on the shelf !
