Dave is right, people who learn to drive stick automatically wiggle the shifter before turning the key.
Some people who were raised in mountain areas even park in first gear each time, and never use the parking brake, because the brakes can freeze...
Of course, if you've had an auto trans daily driver for years and you borrow your mom's stick car because she wants you to test the brakes, you can still shit your pants like I did last week after starting 2 feet from a wall...
Having a clutch safety switch also means you can't push start the car.
I bypassed the safety switch on my 1973 cuda back when my clutch was starting to feel worn, I don't like having to crank "on the clutch".
