Nubo: My 2011 Leaf's "Parking/Emergency Brake" is on the back wheels (not sure whether it's the same for 2013 and later). If I get hit hard enough, won't my car's front wheels be pushed forward (or backward) as well, so isn't it is a question of whether or not the front wheels skid?

If you get hit that hard, your tires skidding is the least of your concerns.

I think it's more a question of whether or not they spin. :)
I noticed you're still working with polymers.

Below 7 mph in the 2011.

I don't recall a post where someone claimed their "Park" position was damaged and no longer keeps their Leaf from moving when parked on a slight/moderate incline. It seems to me the "Emergency/Park Brake" serves a purpose in preventing the back tires from rotating just as the "Park" position prevents the front tires from rotating.

I would expect the tires affected will skid for a time (ABS does not apply) if either is applied when the Leaf is moving, and no damage is done other than "wear and tear" variety.

I have no intention of experimenting trying to find exactly what spped the car goes into park when the button is pushed. I do know this. If you push it at higher speeds, lets say >10mph, it just beeps and stays in d. If you push the power button it just beeps. If you hold the power button for a few seconds, the car completely powers down and keeps rolling.

Good info
Please confirm that it beeps and stay in D and not go into Neutral, when the "P" is pressed above X mph

Power Button (Hold=powers down) raises another question but should know as well. When powered down that method (accidentally) will power steering and brakes looses power as well ?

It's no different than an ICE. The power steering boost will cease but the power brakes have a power reserve that permits a few applications at which point that revert to standard manual brakes.

I'll confirm this next time I drive the car, but first, please kids don't try the holding down the power button while at speed. I read in another thread here that spinning the motor with power off can cause wierd things to happen inside the inverter and fry it. Im lucky my car still runs.

I was right. Pushing park at speed just makes the car go ding. It stays in drive, nothing else happens. Ditto with the power button pressed momentarily.
