Does anyone know how to disable the annoying and useless "Check surroundings for safety...." and subsequent "CAUTION Drive safely and...." screens you see at startup?
We're all stuck with it. Do not know way around it. However, you can turn off beginning and ending piano sound.
I put my car in reverse which displays the backup camera screen. By the time I back out of the driveway and put the car in drive the info screen is gone. No prompt replies required.
I am very annoyed by pop-up messages... although I disabled them unselecting the specific menu item, they bother me usually in the worst moment, such as while I am shutting down the vehicle and the trip computer gives you a summary of the trip, the "door open" message pops up hiding the trip computer message. The worst ones are the ACC preceding veichle proximity messages, on a busy highways these repetitive messages may drive you crazy... distracting instead than being useful. However my 12 years old Lexus does the same so I suppose it is a Japanese safety thing.
I have not seen any start-up display as described in the OP. Is this on the nav screen on the Prius Prime? I have had the start-up sound turned off from day 1 after purchasing the car. Plus I have the screen turned off most of the time, so I guess, never noticed it?
