TLDR version
Don’t be stupid with the clutch; I like the momentary switch idea. I would do that; you could even wire it into a switch that turns on a neutral light. This is basically 1 step away from a remote start system at this point!
No joke, I broke a guy’s leg at AutoZone back in 2007 in Logan Utah with my Chevy S10
I wanted some help adjusting a holley 650 carb I got from them, (it had a sbc 350 swap in it)
I got in enough to put my right foot on the clutch; I thought it was out of gear. I remember checking the stick and it felt good. I was not sitting in the truck, I was standing outside it
The problem with the carb was a high idle issue like 1900 rpm, turns out it was a piece of crap stuck in the float
Anyways, I let my foot of the clutch and it shot forward as the guy was putting the hood up, he jumped up and it pinned his shin on his left leg between my bumper and some sapps bumper who was parked in front of me.
I, being a dumb 20yo, just ruined this guy’s day and possibly his mobility for being a fool and im going to jail I thought to myself!
I helped him as best I could (took my jacket off to keep him warm, it was inter and just above freezing outside, until the ambulance and cops cam. His wife and 1 yo son were on the way to pick him up from work and right before the ambulance came, they roll up and start screaming "OMG OMG OMG OMG" "YOU KILLED MY HUSBAND" The cops came up to me and I put my arms out, they said, NA, it’s a stupid mistake and the guy wasn’t pressing charges.
I literally wanted to die, seeing him in pain and her in tears. FML
Well as it turns out, I went back to see how he was after a month, store manager told me that he got a HUGE settlement from AutoZone's insurance company, like 6 figures. Gave the manager my number so he could reach out to me, a year later I got a call from him, he said, I can break his other leg if I wanted!
