Not looking for help (this time).
Just wondering how simple it would be to design a logic circuit so that youcar starter is disabled while the engine is running. Why haven't they done this. Am I the only idiot that occasionally (maybe a dozen times in my 70 years) turns the key in my ultra quiet running auto?

They do make cars like that, but you could always do a
add on with a vacuum switch to the starter solenoid (NC).

Vacuum switch, no that is truly clever! Thanks.

Count one more idiot here. I consider myself to be a careful,
methodical type. But I still do it, especially when I'm
distracted - at roughly the same frequency as you.

Or a relay driven from a signal from the oil pressure lamp.
If you tap the circuit at the lamp, it will provide a 'high' to drive a
suitable transistor or fet controlling the relay when the motor is running

But that wouldn't work so well because you can create oil pressure
before it starts or if for some reason you are having first crank
starting issues. This is especially true in the winter if your oil
is thick when cold. If you don't get it right on the first crank, you'll
need to wait for the pressure to drop..

hmm, yeah, wire relay to disable the cutout in parallel with the starter relay.
perhap also use a different measure (tacho or altenator aux output)

Most of the cars I have driven have a mechanical interlock in the
ignition lock. Once you have activated the starter, you must turn the
key completely to "off" before you can try to start again.

It's dangerous as hell, too. Once my engine would, occasionally, just
shut off (took months to find the intermittent flywheel sensor). To
restart one had to turn it to the OFF position, which also locks the
steering. Together they are a *BAD* idea.

The operator's manual very explicitly states that you must not turn
the key off while the car is moving.

Also, many cars don't engage the steering lock until you pull the key
completely out of the lock.

Another interesting feature is that the steering lock does not engage
until the steering wheel has been turned a considerable amount off
center:

I really don't give a crap what the manual states. It's *DUMB*.

So you'd better be on a straight road? BTW, that's a dumb idea, too.
The wheels should be straight when parked (it's hard on the power
steering pump to leave them at an angle).

Maybe they do exist, but I've never seen a car where turning the key to
'off' also locked the wheel. I've always had to turn 1 click farther
than 'off' before the wheel locks. I had a Pontiac that was prone to
stalling, and I never needed to even turn it as far as 'off'. Just shift
into neutral and crank the engine until it starts.

BTW, it's *DUMB* (and possibly illegal) to park with your wheels
straight if you are parked on a hill.

So, you're part of the cadre that refuses to RTFM because you're so
smart you don't need to read about the details, and then, when
something goes awry and you get yourself into an accident which hurts
someone else, it's not your fault, of course, it's the dumb manual's?

Sloman was right about you, you're despicable.

I was right about you, Fields, you're illiterate.

What an asshole.
Illiterate idiot.
Even more wisdom from the sage who doesn't seem to know that if you're
parallel parked downhill you should steer into the curb and if you're
parallel parked uphill you should steer away from the curb.

You really are an asshole. ...everyone knows that, even your butt
buddy Slowman.
 
Crikey! krw, You're more ignorant than Ian Field!

krw meets the Ron White criteria of ignorance... "You can't cure
stupid. Stupid is forever!"

You sure know all about that one, intemately, Mr. Alzheimer.
 
You seem to be stuck on that one-word response.

You don't seem to be able to count anymore. Sad, really.
What a laugh. I can run engineering circles around you. Want to
submit to examination ?>:-}

You certainly have it all over everyone in the braggart department,
old man.
Best you can do is name-call.

Just the facts, old man.
Where'd you get that bird-brain idea about power-steering pumps?

Fact, old man.
