I've always considered a suicide clutch to be a clutch pedal that is spring loaded to engage. Sometimes with a pedal cut off. Is this correct?
Scary due to the fact that if you lose your balance or get distracted and put your foot down you'll lurch forward - possibly out into traffic.
*** or a clutch pedal set-up with little resistance. A creeper. It will creep into engagement if you don't keep your foot on it. Would you call that ummm... a potentially hazardous clutch?
A standard non-spring loaded foot clutch is simply refered to as a foot clutch.
