^ Oh gawd, that.
I have ridden with several drivers who have "right ankle seizures" on their gas pedal foot; I swear the first thing to wear out on their vehicles will not be tires, belts, hoses, filters, or bulbs, but the throttle body and linkage. I suspect it is caused by restricted blood circulation to the brain as a result of sitting on it.
This common condition is similar to "right wrist seizures" which for some reason afflicts 98% of Hardley-Ableson riders and 100% of gas leaf blower and chainsaw operators. Modus of causality for this variant seems to be triggered by noise and vibrations.
There are no known cures but conversion to EV may mitigate some symptoms.
