I removed my clutch switch on my 70 Cuda because of the thrust bearing concern. Think about when you're working on your car and for some reason have to crank and crank, thrust bearings don't put up with that for long.

Also, say you have the switch wired up. You get in the habit of depressing the clutch to start, but the absentminded (which is what this safety feature is designed to guard against) then THINKS his car is in neutral and quickly releases the clutch on a RUNNING engine, not realizing its in gear.

Nope, I prefer the pre-ignition check to ensure I'm in neutral thank you.
