Throwout bearings and the fingers on pressure plates tend to receive the most abusive wear from riding the clutch. Fully depressing the pedal, however, while spinning the throughout bearing isn't that traumatic.
The bearing is lubricated and sealed, so unless the seal is defective or worn out, the bearing should last a long, long time. And they almost always make it to clutch replacement.
I have exclusively driven manual transmissions for the last 40 years. And I always keep the pedal depressed in first when stopped; and I have never had any clutch problems as a result. What hurts clutches is abuse.
If the pedal is staying on the floor, it is either the slave cylinder, linkage, clutch cover sticking (unlikely) or some bizarre, but explainable reason.
I have read other posts, where someone was trying to launch real fast and "dumped" the clutch. And at that moment, the clutch stayed on the floor and the car didn't launch. I beleive that is
PSM doing its thing.

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |
