I have to depress the clutch pedal in my Miata to start the engine too. Also had to do that in my ‘85 Chevy Sprint (the precursor to the Geo Metro).
I also prefer driving with three pedals and an H-pattern shifter.
It needs an adjustment or I do because it's easier to stall when starting in low gear, have to gun it a little extra. Otherwise my biggest problem is I keep getting a dead battery because I don't go out for several days at a time.
The other night I was at the grocery store and forgot to turn off my lights, chronic with me. Got my groceries, car won't start. I did it again. So the space is free in front, a car pulls in beside me and I ask him if he can give me a jump start. He said he didn't have any cables. I said I do. So he got off his cell phone call and pulled around.
He couldn't remember how to configure them. I said I thought it was negative me negative you, positive you, ground me, not quite but close. It didn't work. Some younger guy came over and got them on right. Positive me, positive you, negative you, ground me. I think that's the right way.
