Re: Park button (safety concern)

I suggest they do a simple software or hardware modification to reduce the ease of getting to the P button.
1. Maybe they can include a requirement to hold the button for a brief moment (2seconds) before P is activated.
2. Maybe have a confirmation sequence. Like pressing it 2 times
3. Maybe P cannot be activated if the wheel is more than x mph

P.s. Maybe it's already in place but I don't want to find out if it's not.
I don't recommend #1. There have been complaints about Toyota's w/push button start/stop (Smart Key System in Toyota parlance) requiring one push and hold power for several seconds to do an emergency shutdown. It relates to the Saylor Lexus "sudden unintended acceleration"/"stuck throttle" issue that apparently was caused by the wrong floor mat in a loaner he had that entrapped the accelerator pedal and his regular (non-loaner) car not having SKS, but rather a traditional metal key.

I really don't recommend #2.

Seems like requiring either 1 or 2 is an accident waiting to happen. I can't think of any car w/a park button that requires you press Park twice or press and hold. Heck, I've a few times hit it too quickly (or incompletely?) where park didn't engage. I've seen another post here about that.

I also don't agree that the park button is too easy to accidentally press. It's MUCH worse on the Gen 3 Prius.

See these:

It's right below the HVAC buttons and up and to the left of the blue shifter knob.

On a Leaf, I don't see why/how someone would accidentally press park when switching between D and B. I drive around in B on my Leaf pretty much all the time.

Ditto. I accidentally did this while still moving slightly in reverse while backing out of my garage. :shock: Was not a good sound. I am extra careful now.

Thank you

Accidentally isnt it similar to inadvertently

My suggestions or options to make the p less easy to activate was and is a suggestion. What do you recommend?

But since Johnr.. Tested and contributed to this post that it won't activate past a threshold that's the option #3 I posted initially then I'm glad and thank Johnr... For his contribution.

The similar part was the unpleasant mechanical sound. My pressing of Park was intended, so that I could park on my driveway and the reverse beeping would stop. I hadn't intended to shift to D or B at that time. The issue was that I accidentally wasn't at a complete stop.
