It's not safe to nap, but you can do the rest of that.

They're promising 10 seconds of warning when the car wants you to take over.

I wonder how much of those 10 seconds would the car spend trying to notify the driver.

"Warning, take the wheel! Death imminent" takes a good 6 seconds to say :P

[Dylan16807]

I think you should try actually saying that out loud. If I don't pause after the word "wheel", I can say that at a reasonable pace in two seconds.

Just "Warning, take the wheel!" gives you time to pause between each repetition and still say it 5 times.

the “hull alarm” sound from eve online would be perfect for this

Or the Red Alert from Star Trek

Which is roughly 250 meters of car travel time...
