I think the summon feature requires user to keep pressing a button on the phone to work. Lifting finger from the button will stop the car I believe. I’m saying it by watching the videos. Someone knowledgeable do correct if I’m wrong.

You are correct.

So instead of a foot on a pedal connected mostly directly to the brakes, it is a finger on the button of a phone app over the internet? That is madness, imagine if your car's brake pedal had to go over the public internet and instead of a pedal is was a button in a probably poorly coded phone app.

  This is a false problem, the engineer have coded the button the other way: Only moves if you receive a signal from the app. If you lose this information in less than 50ms, just stop the vehicle.

    It's not a solvable problem in this context. Humans are not computers, and cars have no self. The car would melt a hole in the ground and not even approach par with a cat. It's understandable that people are making this mistake in the context of lifetimes of sci-fi anthropomorphizing machines.

    What’s the latency tolerance for this? I have to imagine that, given mobile internet conditions, it’s in the range of seconds. It also raises the question - is it really a dead-man’s switch, or more like a heartbeat being sent every N milliseconds? How many heartbeat signals can be lost? It’s not as simple as a deadman’s switch; it can’t be if it’s using a mobile phone and the internet.

That doesn't stop Tesla from driving into live traffic and stopping there. Look at the videos.
