I thought a "neutral safety switch" was for an automatic transmission. An
"interlock switch" (located at the clutch pedal) is for a manual
transmission. Both prevent starting of the car in gear yada...
Its odd but if you're going to start the car in neutral accidentally
often enoug for it to be a problem, HOW did you pass your test?
I've had an occasion or two when I've been very glad I could start my
car in gear, A helpfull addition to a push when you're on your own. Of
course, much harder with left hand drive cars, as the key isn't next
to the window.
In fact, i seem to recall that this method is in the highway code (the
UK govt 'driving manual') as an emergency procedure to help move the
car to a safe position. Sure, its not great for your starter, but
they're reletively cheap to replace, and if it helps avoid a nasty
accident...
