Depends how you define a failure and what service level you expect
afterwards.

Anyway redundant batteries, fuel pumps and ECUs are quite common in
rally cars.

If you have a double pulley system you have redundant fan belts, as my
car does.

Transmissions have multiple gears. If one goes then you have others. If
clutch goes you can still drive (depending upon failure mechanism) etc. 

Or put it another way. If you work on fighter aircraft you don't deal in
failures, as one is always guaranteed, you deal with mission
survivability.

Can't make every single point of failure redundant on a auto, otherwise
we
would have to carry two of the following:

Batteries
Alternators
Fuel pumps
ECUs
Fan belts
Transmissions
etc

Sometimes you just have to take some risks, and carry a cell phone.
